VARIoT IoT vulnerabilities database

Heap-based buffer overflow in quickTime.qts in Apple QuickTime before 7.4.5 allows remote attackers to execute arbitrary code via a crafted PICT image file, related to an improperly terminated memory copy loop. User interaction is required to exploit this vulnerability in that the target must open a malicious file.The specific flaw exists in the quickTime.qts while parsing corrupted .pict files. The module contains a vulnerable memory copy loop which searches for a terminator value. When this value is changed or omitted, a heap corruption occurs allowing the execution of arbitrary code. These issues arise when the application handles specially crafted Java applets, image files, and movie files. Successful exploits may allow attackers to obtain sensitive information, gain remote unauthorized access in the context of a vulnerable user, and trigger a denial-of-service condition. Versions prior to QuickTime 7.4.5 are affected by these vulnerabilities. Apple QuickTime is a very popular multimedia player. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. 1) An implementation error in QuickTime for Java allows untrusted Java applets to deserialize objects provided by QTJava. This can be exploited to disclose sensitive information or execute arbitrary code e.g. when a user visits a malicious web page. 2) An unspecified error in the handling of external URLs embedded in movie files can lead to information disclosure. 3) An input validation error in the handling of data reference atoms within movie files can be exploited to cause a buffer overflow when a specially crafted movie is viewed. 4) An unspecified error in the handling of movie media tracks can be exploited to cause a memory corruption when a specially crafted movie is viewed. 5) A boundary error in the parsing of "crgn" atoms can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed. 6) A boundary error in the parsing of "chan" atoms can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed. NOTE: This vulnerability does not affect Mac OS X systems. 9) A boundary error in the handling of Animation codec content can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed. NOTE: This vulnerability does not affect Mac OS X systems. 10) A boundary error in the parsing of "obji" atoms can be exploited to cause a stack-based buffer overflow when a specially crafted QuickTime VR movie file is viewed.

Heap-based buffer overflow in quickTime.qts in Apple QuickTime before 7.4.5 on Windows allows remote attackers to execute arbitrary code via a crafted PICT image file with Kodak encoding, related to error checking and error messages. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the quicktime.qts library responsible for parsing Kodak encoded images. A lack of proper error checking can result in a heap based buffer overflow leading to arbitrary code execution under the context of the currently logged in user. These issues arise when the application handles specially crafted Java applets, image files, and movie files. Successful exploits may allow attackers to obtain sensitive information, gain remote unauthorized access in the context of a vulnerable user, and trigger a denial-of-service condition. Versions prior to QuickTime 7.4.5 are affected by these vulnerabilities. Apple QuickTime is a very popular multimedia player. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. 1) An implementation error in QuickTime for Java allows untrusted Java applets to deserialize objects provided by QTJava. This can be exploited to disclose sensitive information or execute arbitrary code e.g. when a user visits a malicious web page. 2) An unspecified error in the handling of external URLs embedded in movie files can lead to information disclosure. 3) An input validation error in the handling of data reference atoms within movie files can be exploited to cause a buffer overflow when a specially crafted movie is viewed. 4) An unspecified error in the handling of movie media tracks can be exploited to cause a memory corruption when a specially crafted movie is viewed. 6) A boundary error in the parsing of "chan" atoms can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed. NOTE: This vulnerability does not affect Mac OS X systems. NOTE: This vulnerability does not affect Mac OS X systems. 10) A boundary error in the parsing of "obji" atoms can be exploited to cause a stack-based buffer overflow when a specially crafted QuickTime VR movie file is viewed.

Heap-based buffer overflow in Apple QuickTime before 7.4.5 allows remote attackers to execute arbitrary code via an MP4A movie with a malformed Channel Compositor (aka chan) atom. User interaction is required to exploit this vulnerability in that the target must visit a malicious page.The specific flaw exists in the parsing of the QuickTime Channel Compositor atom. These issues arise when the application handles specially crafted Java applets, image files, and movie files. Successful exploits may allow attackers to obtain sensitive information, gain remote unauthorized access in the context of a vulnerable user, and trigger a denial-of-service condition. Versions prior to QuickTime 7.4.5 are affected by these vulnerabilities. Apple QuickTime is a very popular multimedia player. There is a heap overflow vulnerability when QuickTime parses the chan atom. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. 1) An implementation error in QuickTime for Java allows untrusted Java applets to deserialize objects provided by QTJava. This can be exploited to disclose sensitive information or execute arbitrary code e.g. when a user visits a malicious web page. 2) An unspecified error in the handling of external URLs embedded in movie files can lead to information disclosure. 3) An input validation error in the handling of data reference atoms within movie files can be exploited to cause a buffer overflow when a specially crafted movie is viewed. 4) An unspecified error in the handling of movie media tracks can be exploited to cause a memory corruption when a specially crafted movie is viewed. 5) A boundary error in the parsing of "crgn" atoms can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed. 7) A boundary error in the handling of PICT records can be exploited to cause a heap-based buffer overflow when a specially crafted PICT image is viewed. 8) A boundary error in the handling of error messages when processing PICT images can be exploited to cause a heap-based buffer overflow. NOTE: This vulnerability does not affect Mac OS X systems. 9) A boundary error in the handling of Animation codec content can be exploited to cause a heap-based buffer overflow when a specially crafted movie file is viewed. NOTE: This vulnerability does not affect Mac OS X systems. 10) A boundary error in the parsing of "obji" atoms can be exploited to cause a stack-based buffer overflow when a specially crafted QuickTime VR movie file is viewed. 11) A boundary error in the parsing of the Clip opcode can be exploited to cause a heap-based buffer overflow when a specially crafted PICT image file is viewed. Successful exploitation of these vulnerabilities may allow execution of arbitrary code. SOLUTION: Update to version 7.4.5.

Stack-based buffer overflow in the AutoFix Support Tool ActiveX control 2.7.0.1 in SYMADATA.DLL in multiple Symantec Norton products, including Norton 360 1.0, AntiVirus 2006 through 2008, Internet Security 2006 through 2008, and System Works 2006 through 2008, allows remote attackers to execute arbitrary code via a long argument to the GetEventLogInfo method. NOTE: some of these details are obtained from third party information. Symantec AutoFix Support Tool ActiveX control is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. An attacker can exploit this issue to execute arbitrary code in the context of an application using the ActiveX control (typically Internet Explorer). Failed attacks will likely cause denial-of-service conditions. NOTE: To exploit this issue, an attacker must entice an unsuspecting victim to to visit a malicious website masquerading as a trusted Symantec site. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released.

BACKGROUND Norton Internet Security 2008 is a system security suite that offers protection from spyware, viruses, identity theft, spam, and malicious network traffic. More information can be found on the vendor's site at the following URL. http://www.symantec.com/home_homeoffice/products/overview.jsp?pcid=is&pvid=nis2008 II. III. In order for exploitation to occur, an attacker would have to lure a vulnerable user to a malicious web site. While this control is marked as safe for scripting, the control has been designed so that it can only be run from the "symantec.com" domain. In practice this requirement can be bypassed through the use of any Cross Site Scripting (XSS) vulnerabilities in the Symantec domain. Exploitation could also occur through the use of DNS poisoning attacks. IV. DETECTION iDefense confirmed that this vulnerability exists in version 2.7.0.1 of the control that is installed with the 2008 version of Norton Internet Security. Other versions may also be available. V. WORKAROUND Setting the kill-bit for this control will prevent it from being loaded within Internet Explorer. However, doing so will prevent legitimate use of the control. VI. VENDOR RESPONSE Symantec has addressed this vulnerability by releasing updates. For more information, refer to their advisory at the following URL. http://www.symantec.com/avcenter/security/Content/2008.04.02a.html VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2008-0312 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII.

The ActiveDataInfo.LaunchProcess method in the SymAData.ActiveDataInfo.1 ActiveX control 2.7.0.1 in SYMADATA.DLL in multiple Symantec Norton products including Norton 360 1.0, AntiVirus 2006 through 2008, Internet Security 2006 through 2008, and System Works 2006 through 2008, does not properly determine the location of the AutoFix Tool, which allows remote attackers to execute arbitrary code via a remote (1) WebDAV or (2) SMB share. An ActiveX control in the Symantec AutoFix Tool is prone to a vulnerability due to an insecure method. Attackers can leverage this issue to load an arbitrary file onto a victim's computer and then execute it with the privileges of the application running the control (typically Internet Explorer). This issue is exploitable only when a victim's computer is configured to allow remote connections to WebDav or SMB shares. Successful exploits will compromise affected computers. iDefense Security Advisory 04.02.08 http://labs.idefense.com/intelligence/vulnerabilities/ Apr 02, 2008 I.

The virtual private dial-up network (VPDN) component in Cisco IOS before 12.3 allows remote attackers to cause a denial of service (resource exhaustion) via a series of PPTP sessions, related to the persistence of interface descriptor block (IDB) data structures after process termination, aka bug ID CSCdv59309. A vulnerability in the way Cisco IOS handles IPv6 packets could result in a remotely exploitable denial of service. Cisco IOS is prone to multiple denial-of-service vulnerabilities that occur in the virtual private dial-up (VPDN) when the Point-to-Point Tunneling Protocol (PPTP) is enabled. Successfully exploiting these issues may cause a memory leak or prevent the establishment of VPDN connections, denying service to legitimate users. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. 3) Some errors exist in the Data-Link-Switching (DLSw) feature when processing UDP and IP protocol 91 packets. 4) An error exists in the processing of IPv6 packets, which can be exploited to prevent the interface from receiving additional traffic or to cause the device to crash (if RSVP service is configured on the interface) by sending a specially crafted IPv6 packet to the device. Successful exploitation of this vulnerability requires that IPv6 and certain IPv4 UDP services are enabled. 5) An error exists in the implementation of Multicast Virtual Private Networks (MVPN), which can be exploited to create extra multicast states on the core routers via specially crafted Multicast Distribution Tree (MDT) Data Join messages. This can also be exploited to receive multicast traffic from VPNs that are not connected to the same Provider Edge (PE). Successful exploitation of the multicast traffic leak requires that the attacker knows or guesses the Border Gateway Protocol (BGP) peering IP address of a remote PE router and the address of the multicast group that is used in other MPLS VPNs. SOLUTION: Update to the fixed version (please see the vendor's advisories for details). 5) The vendor credits Thomas Morin.

PPTP is only one of the supported tunneling protocols used to tunnel PPP frames within the VPDN solution. The first vulnerability is a memory leak that occurs as a result of PPTP session termination. The second vulnerability may consume all interface descriptor blocks on the affected device because those devices will not reuse virtual access interfaces. If these vulnerabilities are repeatedly exploited, the memory and/or interface resources of the attacked device may be depleted. Cisco has made free software available to address these vulnerabilities for affected customers. There are no workarounds available to mitigate the effects of these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080326-pptp.shtml Note: The March 26, 2008 publication includes five security advisories. The advisories all address vulnerabilities in Cisco's Internetwork Operating System (IOS) software. Each advisory lists the releases that correct the vulnerability described in the advisory, and also lists the releases that correct the vulnerabilities in the other five advisories. Please reference the following software table to find a release that fixes all published software advisories as of March 26th, 2008: * March 26th Bundled IOS Advisory Table http://www.cisco.com/warp/public/707/cisco-sa-20080326-bundle.shtml Individual publication links are listed below: * Cisco IOS Virtual Private Dial-up Network Denial of Service Vulnerability http://www.cisco.com/warp/public/707/cisco-sa-20080326-pptp.shtml * Multiple DLSw Denial of Service Vulnerabilities in Cisco IOS http://www.cisco.com/warp/public/707/cisco-sa-20080326-dlsw.shtml * Cisco IOS User Datagram Protocol Delivery Issue For IPv4/IPv6 Dual-stack Routers http://www.cisco.com/warp/public/707/cisco-sa-20080326-IPv4IPv6.shtml * Vulnerability in Cisco IOS with OSPF, MPLS VPN, and Supervisor 32, Supervisor 720, or Route Switch Processor 720 http://www.cisco.com/warp/public/707/cisco-sa-20080326-queue.shtml * Cisco IOS Multicast Virtual Private Network (MVPN) Data Leak http://www.cisco.com/warp/public/707/cisco-sa-20080326-mvpn.shtml Affected Products ================= Devices that are running certain Cisco IOS versions prior to 12.3 with VPDN enabled may be affected by these vulnerabilities. Vulnerable Products +------------------ Devices that are running affected versions of Cisco IOS with VPDN enabled and are configured to accept termination of PPTP sessions are vulnerable. To determine whether VPDN is enabled on your device, log in to the device and issue the command-line interface (CLI) command "show running-config". If the output contains "vpdn enable" along with a "vpdn-group <name>" command, VPDN is enabled on the device. The device will accept termination of PPTP sessions if the command "protocol any" or "protocol pptp" is defined under the "vpdn-group <name>" command. The following example shows a device that is running VPDN and will accept termination of PPTP sessions: Router#show running-config Building configuration... ! !--- Output truncated. ! vpdn enable ! vpdn-group test_only ! Default PPTP VPDN group accept-dialin protocol pptp virtual-template 1 ! !---Remaining output truncated. To determine the software version running on a Cisco product, log in to the device and issue the "show version" command to display the system banner. Cisco IOS software will identify itself as "Internetwork Operating System Software" or simply "IOS." On the next line of output, the image name will be displayed between parentheses, followed by "Version" and the IOS release name. Other Cisco devices will not have the "show version" command or will give different output. The following example identifies a Cisco product that is running Cisco IOS release 12.2(7): Cisco Internetwork Operating System Software IOS (tm) 7200 Software (C7200-IS-M), Version 12.2(7), RELEASE SOFTWARE (fc1) Copyright (c) 1986-2002 by cisco Systems, Inc. Compiled Tue 15-Jan-02 18:31 by pwade Image text-base: 0x600089C0, data-base: 0x613A6000 Additional information about Cisco IOS release naming can be found at http://www.cisco.com/warp/public/620/1.html. Products Confirmed Not Vulnerable +-------------------------------- Devices that are running Cisco IOS versions 12.3 and later are not affected by these vulnerabilities. Devices that are explicitly configured for VPDN protocols other than PPTP are not affected. Devices that are running Cisco IOS versions prior to 12.3 and do not have VPDN enabled are not affected by these vulnerabilities. Cisco IOS XR is not affected by these vulnerabilities. Details ======= VPDNs securely carry private data over a public network, allowing remote users to access a private network over a shared infrastructure such as the Internet. VPDNs maintain the same security and management policies as a private network, while providing a cost-effective method for point-to-point connections between remote users and a central network. PPTP is a network protocol that enables the secure transfer of data from a remote client to a private enterprise server by creating a VPDN across TCP/IP-based data networks. PPTP supports on-demand, multiprotocol, virtual private networking over public networks, such as the Internet. Details regarding the two known vulnerabilities in Cisco IOS devices that are running affected versions of system software follow: * Memory Leak due to PPTP Session Termination Upon completion of a PPTP session, memory is leaked from the processor memory on the terminating device. This is shown in the output of "show process memory" under the *Dead* process. The *Dead* process is not a real process. Its function is to account for the memory that is allocated under the context of another process which has terminated, in this case PPTP. When the administrator is logged into the device, if the device is under exploitation, the Holding entry of the *Dead* process under the "show process memory" command will be increasing. Following is an example showing a device that is holding *Dead* memory: Router#show process memory Total: 199718560, Used: 11147828, Free: 188570732 PID TTY Allocated Freed Holding Getbufs Retbufs Process 0 0 99812 1848 8415816 0 0 *Init* 0 0 444 778840 444 0 0 *Sched* 0 0 17481700 4930848 819672 180908 0 *Dead* 1 0 284 284 3828 0 0 Load Meter !--- Output truncated. The CLI command "show memory dead" allows administrators to examine the contents of *Dead*. The output will display many occurrences of PPTP in the output if the PPTP process is causing the leak. The following example shows the dead memory for a device that has been exploited by the vulnerability Router#show memory dead Head Total(b) Used(b) Free(b) Lowest(b) Largest(b) Processor 6225FF40 224002240 11906736 212095504 212082872 212084464 I/O 20000000 33554440 994136 32560304 32560304 32560252 I/O-2 F800000 8388616 1020632 7367984 7367984 7367932 Processor memory Address Bytes Prev Next Ref PrevF NextF Alloc PC what 62275DC8 0000000048 62275D68 62275E24 001 ------- ------- 60654230 PPTP create idb 62275E24 0000000052 62275DC8 62275E84 001 ------- ------- 60654230 PPTP create idb 62275E84 0000000052 62275E24 62275EE4 001 ------- ------- 60654230 PPTP create idb .... !--- remaining output truncated. This vulnerability is documented in Cisco bug ID CSCsj58566 and Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-1151 has been assigned to this vulnerability. * Virtual Access Interfaces Are Not Re-used Upon completion of a PPTP session, affected devices do not remove the virtual access interface that is associated with the PPTP session and do not reuse the interfaces in any future connections. This situation can result in an exhaustion of the interface descriptor block (IDB) limit, which will prevent any new interfaces being created within Cisco IOS, effectively blocking all new VPDN connections, even though the router may still have enough processor memory to remain up and running. A reload of the device is required to remove the interfaces. An IDB is a Cisco IOS internal data structure that contains information such as the IP address, interface state, and packet statistics. Cisco IOS software maintains one IDB for each interface present on a platform and one IDB for each subinterface. Further documentation on Cisco IOS IDBs can be found at: http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_tech_note09186a0080094322.shtml This vulnerability is documented in Cisco bug ID CSCdv59309 and Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-1150 has been assigned to this vulnerability. Vulnerability Scoring Details ============================= Cisco is providing scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. Cisco will provide a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. CVSS is a standards based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided an FAQ to answer additional questions regarding CVSS at http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at http://intellishield.cisco.com/security/alertmanager/cvss CSCsj58566 - Memory Leak due to PPTP Session Termination CVSS Base Score - 7.1 Access Vector: Network Access Complexity: Medium Authentication: None Confidentiality Impact: None Integrity Impact: None Availability Impact: Complete CVSS Temporal Score - 5.9 Exploitability: Functional Remediation Level: Official-Fix Report Confidence: Confirmed CSCdv59309 - Virtual Access Interfaces Are Not Re-used CVSS Base Score - 4.3 Access Vector: Network Access Complexity: Medium Authentication: None Confidentiality Impact: None Integrity Impact: None Availability Impact: Partial CVSS Temporal Score - 3.6 Exploitability: Functional Remediation Level: Official-Fix Report Confidence: Confirmed Impact ====== Successful exploitation of the vulnerability may result in a memory leak of processor memory or consumption of all available IDBs on the device. With continued exploitation, the device will deplete its processor memory or reach an IDB limit. Both impacts would result in a denial of service condition for the device. Software Versions and Fixes =========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center ("TAC") or your contracted maintenance provider for assistance. Each row of the Cisco IOS software table (below) names a Cisco IOS release train. If a given release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table. +----------------------------------------+ | Major | Availability of Repaired | | Release | Releases | |------------+---------------------------| | Affected | First Fixed | Recommended | | 12.0-Based | Release | Release | | Releases | | | |------------+-------------+-------------| | 12.0 | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0DA | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0DB | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0DC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0S | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SL | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SP | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0ST | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SX | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SY | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SZ | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0T | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0W | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0WC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0WT | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0XA | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0XB | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0XC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0XD | Not | | | | Vulnerable | | |------------+-------------+-------------| | | Releases | | | | prior to | | | | 12.0(7)XE2 | | | | are | | | 12.0XE | vulnerable, | | | | release | | | | 12.0(7)XE2 | | | | and later | | | | are not | | | | vulnerable;

The data-link switching (DLSw) component in Cisco IOS 12.0 through 12.4 allows remote attackers to cause a denial of service (device restart or memory consumption) via crafted (1) UDP port 2067 or (2) IP protocol 91 packets. A vulnerability in the way Cisco IOS handles IPv6 packets could result in a remotely exploitable denial of service. Cisco IOS is prone to multiple remote denial-of-service vulnerabilities because the software fails to properly handle malformed network datagrams. Successfully exploiting these issues allows remote attackers to trigger memory leaks or crashes in targeted devices. This will lead to denial-of-service conditions. These issues are tracked by Cisco Bug ID CSCsk73104. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. 1) A memory leak exists in the handling of completed PPTP sessions, which can be exploited to exhaust memory on an affected system. 2) An error exists in the handling of PPTP sessions when virtual access interfaces are not removed from the interface descriptor block (IDB) and are not reused. This can result in an exhaustion of the interface descriptor block (IDB) limit. This can be exploited to cause a reload of the system or a memory leak. Successful exploitation of this vulnerability requires that IPv6 and certain IPv4 UDP services are enabled. 5) An error exists in the implementation of Multicast Virtual Private Networks (MVPN), which can be exploited to create extra multicast states on the core routers via specially crafted Multicast Distribution Tree (MDT) Data Join messages. This can also be exploited to receive multicast traffic from VPNs that are not connected to the same Provider Edge (PE). Successful exploitation of the multicast traffic leak requires that the attacker knows or guesses the Border Gateway Protocol (BGP) peering IP address of a remote PE router and the address of the multicast group that is used in other MPLS VPNs. SOLUTION: Update to the fixed version (please see the vendor's advisories for details).

This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080326-dlsw.shtml Note: The March 26, 2008 publication includes five Security Advisories. The Advisories all affect Cisco's Internetwork Operating System (IOS). Each Advisory lists the releases that correct the vulnerability described in the Advisory, and the Advisories also detail the releases that correct the vulnerabilities in all five Advisories. Please reference the following software table to find a release which fixes all published Security Advisories as of March 26th, 2008. * March 26th bundled IOS Advisory Table http://www.cisco.com/warp/public/707/cisco-sa-20080326-bundle.shtml Individual publication links are listed below: * Cisco IOS Virtual Private Dial-up Network Denial of Service Vulnerability http://www.cisco.com/warp/public/707/cisco-sa-20080326-pptp.shtml * Multiple DLSw Denial of Service Vulnerabilities in Cisco IOS http://www.cisco.com/warp/public/707/cisco-sa-20080326-dlsw.shtml * Cisco IOS User Datagram Protocol Delivery Issue For IPv4/IPv6 Dual-stack Routers http://www.cisco.com/warp/public/707/cisco-sa-20080326-IPv4IPv6.shtml * Vulnerability in Cisco IOS with OSPF, MPLS VPN, and Supervisor 32, Supervisor 720, or Route Switch Processor 720 http://www.cisco.com/warp/public/707/cisco-sa-20080326-queue.shtml * Cisco IOS Multicast Virtual Private Network (MVPN) Data Leak http://www.cisco.com/warp/public/707/cisco-sa-20080326-mvpn.shtml Affected Products ================= Vulnerable Products +------------------ This security advisory applies to all Cisco products that run any version of affected Cisco IOS software configured for DLSw. Systems that contain the DLSw feature, but do not have it enabled, are not affected. Routers enabled for DLSw contain a line in the configuration defining a local DLSw peer. This configuration can be observed by issuing the command "show running-config". Systems configured for DLSw contain lines similar to the following: "dlsw local-peer" or "dlsw local-peer peer-id <IP address>" Any version of Cisco IOS prior to the versions which are listed in the Software Versions and Fixes section below is vulnerable. To determine the version of Cisco IOS software running on a Cisco product, log in to the device and issue the show version command to display the system banner. Cisco IOS Software will identify itself as "Internetwork Operating System Software" or simply "IOS". On the next line of output, the image name will be displayed between parentheses, followed by "Version" and the IOS release name. Other Cisco devices will not have the "show version" command or will give different output. The following example identifies a Cisco product running Cisco IOS Software Release 12.3(6) with an installed image name of C3640-IS-M: Cisco Internetwork Operating System Software IOS (tm) 3600 Software (C3640-IS-M), Version 12.3(6), RELEASE SOFTWARE (fc3) The next example shows a product running Cisco IOS Software Release 12.3(11)T3 with an image name of C3845-ADVIPSERVICESK9-M: Cisco IOS Software, 3800 Software (C3845-ADVIPSERVICESK9-M), Version 12.3(11)T3, RELEASE SOFTWARE (fc4) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2005 by Cisco Systems, Inc. Additional information about Cisco IOS release naming can be found at http://www.cisco.com/warp/public/620/1.html. Products Confirmed Not Vulnerable +-------------------------------- Cisco IOS devices that are not configured for DLSw are not vulnerable. No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= Data-link switching (DLSw) provides a means of transporting IBM Systems Network Architecture (SNA) and network basic input/output system (NetBIOS) traffic over an IP network. Cisco implementation of DLSw also uses UDP port 2067 and IP Protocol 91 for Fast Sequenced Transport (FST). These vulnerabilities do not affect TCP packet processing. A successful exploitation may result in a reload of the system or a memory leak on the device, leading to a denial of service (DoS) condition. Cisco IOS devices configured for DLSw with "dlsw local-peer" automatically listen for IP protocol 91 packets. Cisco IOS devices listen to IP protocol 91 packets when DLSw is configured. However, it is only used if DLSw is configured for Fast Sequenced Transport (FST). A DLSw FST peer configuration will contain the following line: "dlsw remote-peer 0 fst <ip-address>" It is possible to disable UDP processing in DLSw with the "dlsw udp-disable" command. However, disabling UDP only prevents the sending of UDP packets, it does not prevent the device from receiving and processing incoming UDP packets. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at http://intellishield.cisco.com/security/alertmanager/cvss CSCsk73104 - Handling of malformed packets by DLSW CVSS Base Score - 7.8 Access Vector: Network Access Complexity: Low Authentication: None Confidentiality Impact: None Integrity Impact: None Availability Impact: Complete CVSS Temporal Score - 6.4 Exploitability: Functional Remediation Level: Official-Fix Report Confidence: Confirmed Impact ====== Successful exploitation of these vulnerabilities may result in the reload of the device or memory leaks, leading to a DoS condition. Software Versions and Fixes =========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the Cisco IOS software table (below) names a Cisco IOS release train. If a given release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table. +----------------------------------------+ | Major | Availability of Repaired | | Release | Releases | |------------+---------------------------| | Affected | First Fixed | Recommended | | 12.0-Based | Release | Release | | Releases | | | |------------+-------------+-------------| | | Vulnerable;

Workarounds =========== The workaround consists of filtering UDP packets to port 2067 and IP protocol 91 packets. Filters can be applied at network boundaries to filter all IP protocol 91 packets and UDP packets to port 2067 or can be applied on individual affected devices to permit such traffic only from trusted peer IP addresses. However, since both of the protocols are connectionless, it is possible for an attacker to spoof malformed packets from legitimate peer IP addresses. As soon as DLSw is configured, the Cisco IOS device begins listening on IP protocol 91. However, this protocol is only used if DLSw is configured for Fast Sequenced Transport (FST). A DLSw FST peer configuration will contain the following line: "dlsw remote-peer 0 fst <ip-address>" If FST is used, filtering IP protocol 91 will break the operation, so filters need to permit protocol 91 traffic from legitimate peer IP addresses. It is possible to disable UDP processing in DLSw with the "dlsw udp-disable" command. However, disabling UDP only prevents the sending of UDP packets, it does not prevent the receiving and processing of incoming UDP packets. To protect a vulnerable device from malicious packets via UDP port 2067, both of the following actions must be taken: 1. Disable UDP outgoing packets with the "dlsw udp-disable" command, AND 2. Filter UDP 2067 in the vulnerable device using infrastructure ACL. Additional mitigation techniques that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory: http://www.cisco.com/warp/public/707/cisco-amb-20080326-dlsw.shtml Using Control Plane Policing on Affected Devices +----------------------------------------------- Control Plane Policing (CoPP) can be used to block untrusted DLSw traffic to the device. Cisco IOS software releases 12.0S, 12.2SX, 12.2S, 12.3T, 12.4, and 12.4T support the CoPP feature. CoPP may be configured on a device to protect the management and control planes to minimize the risk and effectiveness of direct infrastructure attacks by explicitly permitting only authorized traffic sent to infrastructure devices in accordance with existing security policies and configurations. The following example, which uses 192.168.100.1 to represent a trusted host, can be adapted to your network. If FST is not used, protocol 91 may be completely filtered.

Using Infrastructure ACLs at Network Boundary +-------------------------------------------- Although it is often difficult to block traffic transiting your network, it is possible to identify traffic that should never be allowed to target your infrastructure devices and block that traffic at the border of your network. iACLs are a network security best practice and should be considered as a long-term addition to good network security as well as a workaround for this specific vulnerability. The iACL example shown below should be included as part of the deployed infrastructure access-list that will protect all devices with IP addresses in the infrastructure IP address range. If FST is not used, protocol 91 may be completely filtered. Additionally, if UDP is disabled with the "dlsw udp-disable" command, UDP port 2067 may also be completely filtered. !--- Permit DLSw (UDP port 2067 and IP protocol 91) packets !--- from trusted hosts destined to infrastructure addresses. access-list 150 permit udp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 2067 access-list 150 permit 91 TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK !--- Deny DLSw (UDP port 2067 and IP protocol 91) packets from !--- all other sources destined to infrastructure addresses. access-list 150 deny udp any INFRASTRUCTURE_ADDRESSES MASK eq 2067 access-list 150 deny 91 any INFRASTRUCTURE_ADDRESSES MASK !--- Permit/deny all other Layer 3 and Layer 4 traffic in accordance !--- with existing security policies and configurations !--- Permit all other traffic to transit the device. access-list 150 permit ip any any interface serial 2/0 ip access-group 150 in The white paper entitled "Protecting Your Core: Infrastructure Protection Access Control Lists" presents guidelines and recommended deployment techniques for infrastructure protection access lists.

Unspecified vulnerability in the Supervisor Engine 32 (Sup32), Supervisor Engine 720 (Sup720), and Route Switch Processor 720 (RSP720) for multiple Cisco products, when using Multi Protocol Label Switching (MPLS) VPN and OSPF sham-link, allows remote attackers to cause a denial of service (blocked queue, device restart, or memory leak) via unknown vectors. An attacker can exploit this issue to prevent any traffic from entering affected devices, causing denial-of-service conditions for legitimate users. The following devices are affected: Cisco Catalyst 6500 Series devices with the Sup32, Sup720, Sup720-3B, or Sup720-3BXL Cisco 7600 Series devices with the Sup32, Sup720, Sup720-3B, or Sup720-3BXL Cisco 7600 Series devices with the RSP720, RSP720-3C, or RSP720-3CXL Cisco ME 6524 Ethernet Switch Some Cisco IOS branches based on 12.2 are vulnerable only when combined with hardware based on specific Catalyst Supervisor Engines (Sup32, Sup720, or RSP720) and configured with MPLS VPN and OSPF sham-link. NOTE: OSPF and MPLS VPN are not enabled by default. Cisco IOS is the Internet operating system used in Cisco networking equipment. In addition to possibly blocked interface queues, devices may also experience memory leaks or reboots. In the case of a memory leak, the device cannot forward traffic once it has exhausted the available memory. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. The vulnerability is caused due to an unspecified error in the handling of certain packets and can be exploited to cause a blocked interface input queue, a memory leak, or a restart of the device.

Cisco IOS 12.1, 12.2, 12.3, and 12.4, with IPv4 UDP services and the IPv6 protocol enabled, allows remote attackers to cause a denial of service (device crash and possible blocked interface) via a crafted IPv6 packet to the device. Cisco IOS-based dual-stack routers are prone to a denial-of-service vulnerability. This issue can occur when a specially crafted IPv6 packet is sent to the device. A successful exploit may cause the affected interface to stop responding, or in some scenarios, may crash the device. Cisco has assigned Bug ID CSCse56501 to this vulnerability. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Cisco Security Advisory: Cisco IOS User Datagram Protocol Delivery Issue For IPv4/IPv6 Dual-stack Routers Advisory ID: cisco-sa-20080326-IPv4IPv6 http://www.cisco.com/warp/public/707/cisco-sa-20080326-IPv4IPv6.shtml Revision 1.0 For Public Release 2008 March 26 1600 UTC (GMT) Summary ======= A device running Cisco IOS software that has Internet Protocol version 6 (IPv6) enabled may be subject to a denial of service (DoS) attack. Packets that are routed throughout the router can not trigger this vulnerability. Successful exploitation will prevent the interface from receiving any additional traffic. Only the interface on which the vulnerability was exploited will be affected. Cisco is providing fixed software to address this issue. There are workarounds available to mitigate the effects of the vulnerability. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080326-IPv4IPv6.shtml Note: The March 26, 2008 publication includes five Security Advisories. The Advisories all affect Cisco's Internetwork Operating System (IOS). Each Advisory lists the releases that correct the vulnerability described in the Advisory, and the Advisories also detail the releases that correct the vulnerabilities in all five Advisories. Please reference the following software table to find a release which fixes all published Security Advisories as of March 26th, 2008. The IPv6 is not enabled by default in Cisco IOS software. To determine the software running on a Cisco IOS product, log in to the device and issue the show version command to display the system banner. Cisco IOS software will identify itself as "Internetwork Operating System Software" or simply "IOS." On the next line of output, the image name will be displayed between parentheses, followed by "Version" and the Cisco IOS software release name. Other Cisco devices will not have the show version command, or will give different output. The following example shows output from a device running a Cisco IOS image: Router>show version Cisco IOS Software, 1841 Software (C1841-ADVSECURITYK9-M), Version 12.4(15)T2, RELEASE SOFTWARE (fc7) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2008 by Cisco Systems, Inc. Compiled Thu 17-Jan-08 23:12 by prod_rel_team Additional information about Cisco IOS software release naming is available at the following link: http://www.cisco.com/en/US/products/sw/iosswrel/ps1828/products_white_paper09186a008018305e.shtml. In order for an interface to be vulnerable two conditions must be satisfied: 1. An interface must have IPv6 enabled. 2. One or more of the following IPv4 UDP-based services must be enabled: TACACS - port 49 Domain Name System (DNS) server - port 53 Resource Reservation Protocol (RSVP) - port 1698 Layer Two Forwarding (L2F)/Layer Two Tunnel Protocol (L2TP) - port 1701 IP SLA Responder - port 1967 Media Gateway Control Protocol (MGCP) - port 2427 Session Initiation Protocol (SIP) - port 5060 No other IPv4 UDP-based services are known to be affected. How To Verify If IPv6 Is Enabled +------------------------------- IPv6 protocol is enabled on an interface if either or both of the following configuration lines are present in the configuration: Router#show running-config interface FastEthernet0/1 ipv6 address 2001:0DB8:C18:1::/64 eui-64 Router#show running-config interface FastEthernet0/1 ipv6 enabled If any of the interfaces contain either or both of the ipv6 lines then IPv6 is enabled on that particular interface. In some newer IOS releases the command show ip sockets is obsoleted, and the alternate command show udp can be used instead. The output is identical to the show ip sockets command. The device is vulnerable if the Local Port column (fifth from the left) in the output of show ip sockets contains any of the port numbers listed in the example below. Router#show ip sockets Proto Remote Port Local Port In Out Stat TTY OutputIF 17 192.168.100.1 49 192.168.100.2 49 0 0 11 0 17 0.0.0.0 0 192.168.100.2 53 0 0 211 0 17 --listen-- 192.168.100.2 1698 0 0 1 0 17 192.168.100.1 1701 192.168.100.2 1701 1 0 1021 0 17 0.0.0.0 0 192.168.100.2 1967 0 0 211 0 17 0.0.0.0 0 --any-- 2427 0 0 211 0 17 0.0.0.0 0 --any-- 5060 0 0 211 0 Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products are currently known to be affected by this vulnerability. Cisco IOS XR and Cisco PIX/ASA are not affected. Packets that are routed throughout the router can not trigger this vulnerability. Successful exploitation of the vulnerability may result in one of the following two conditions: 1. The device will crash if RSVP service is configured on the interface. 2. Any other affected IPv4 UDP-based service will prevent the interface from receiving additional traffic. Only the interface on which the vulnerability is exploited will be affected. This vulnerability is independent of the interface media type. It is possible to unblock the interface using methods other than a device reload. These methods are described in the Workarounds section. All other interfaces are unaffected and will continue receiving and transmitting packets. Blocked interface may allow transit traffic to flow for a period of time. Transit traffic may continue to flow until either the respective routing entry or Address Resolution Protocol (ARP) entry expires, whichever event occurs first. Depending on the circumstances the transit traffic can stop flowing through the blocked interface within a few seconds or continue up to four hours (which is the ARP cache default lifetime). After that no further transit traffic will flow through the blocked interface. No other IPv4 UDP-based services are known to be affected by this vulnerability. Identification Of Vulnerability Exploitation +------------------------------------------- The show interfaces command can be used to view the input queue size to identify a blocked input interface. A device under attack, but not yet blocked will show the Input queue size increasing without a subsequent decrease. If the current size (in this case, 76) is larger than the maximum size (75), the input queue is blocked. The value of 75 is the default value and it can be changed using the interface command hold-queue X in . Router#show interfaces FastEthernet 0/1 | include queue Input queue: 76/75/0/0 (size/max/drops/flushes); Total output drops: 0 Output queue: 0/40 (size/max) The example above shows that the interface FastEthernet0/1 is blocked. The show ip sockets command can be used to determine which protocol blocks the interface. If In column (sixth from the left) of the output contains any other number than zero (0) that is an indication that packets of that particular protocol are blocking, or starting to block, the interface. The following example shows DNS packets that are beginning to fill the input queue of the interface. The interface is not completely blocked because only 13 packets are in the input queue. Router#show ip sockets Proto Remote Port Local Port In Out Stat TTY OutputIF 17 192.168.100.1 49 192.168.100.2 49 0 0 11 0 17 0.0.0.0 0 192.168.100.2 53 13 0 211 0 17 --listen-- 192.168.100.2 1698 0 0 1 0 17 192.168.100.1 1701 192.168.100.2 1701 1 0 1021 0 17 0.0.0.0 0 192.168.100.2 1967 0 0 211 0 17 0.0.0.0 0 --any-- 2427 0 0 211 0 17 0.0.0.0 0 --any-- 5060 0 0 211 0 The output of the show ip sockets command does not provide information on interfaces. It is possible that packets from multiple protocols may be blocking a single interface. The output of the command must be interpreted with the device's configuration to establish the affected port. Additional methods that can be used to detect blocked interfaces are described in "Cisco Applied Mitigation Bulletin: User Datagram Protocol Delivery Issue For IPv4/IPv6 Dual-Stack Routers" document available at http://www.cisco.com/warp/public/707/cisco-amb-20080326-IPv4IPv6.shtml. The method utilizes Embedded Event Manager (EEM) and Applets or an EEM Script. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at http://intellishield.cisco.com/security/alertmanager/cvss CSCse56501 - UDP delivery issue when IPv4 and IPv6 are bound to the same socket CVSS Base Score - 7.8 Access Vector - Network Access Complexity - Low Authentication - None Confidentiality Impact - None Integrity Impact - None Availability Impact - Complete CVSS Temporal Score - 6.4 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the vulnerability can result in one of the following two conditions: 1. The device will crash if RSVP service is configured on the interface. 2. Any other affected IPv4 UDP-based service will prevent the interface from receiving additional traffic. Only the interface on which the vulnerability is exploited will be affected. Software Versions and Fixes =========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the Cisco IOS software table (below) names a Cisco IOS release train. If a given release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table. +----------------------------------------+ | Major | Availability of Repaired | | Release | Releases | |------------+---------------------------| | Affected | First Fixed | Recommended | | 12.0-Based | Release | Release | | Releases | | | |----------------------------------------| | There are no affected 12.0 based | | releases | |----------------------------------------| | Affected | First Fixed | Recommended | | 12.1-Based | Release | Release | | Releases | | | |------------+-------------+-------------| | 12.1 | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1AA | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1AX | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1AY | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1AZ | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1CX | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1DA | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1DB | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1DC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1E | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1EA | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1EB | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1EC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1EO | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1EU | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1EV | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1EW | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1EX | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1EY | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1EZ | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1GA | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1GB | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1T | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XA | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XB | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XD | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XE | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XF | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XG | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XH | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XI | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XJ | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XK | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XL | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XM | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XN | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XO | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XP | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XQ | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XR | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XS | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.1XT | Not | | | | Vulnerable | | |------------+-------------+-------------| | | Vulnerable;

This procedure can restore normal operation of the interface without rebooting the device. The procedure for disabling vulnerable services are described in the "If IPv4 UDP-based Services Are Not Required" section. The following workarounds are options that may be available depending on the Cisco IOS software running on the device and the operating environment. If IPv6 Protocol Is Not Required +------------------------------- Disable IPv6. To disable IPv6 use the following commands: Router(config)#interface FastEthernet0/0 Router(config-if)#no ipv6 address or Router(config)#interface FastEthernet0/0 Router(config-if)#no ipv6 enable If RSVP is the only affected service that is configured it is sufficient to disable IPv6 only on the interface where RSVP is configured. If IPv4 UDP-based Services Are Not Required +------------------------------------------ Disable all affected IPv4 UDP-based services. Disabling TACACS +--------------- To disable TACACS use the following commands: Router(config)#no tacacs-server host <IP-address> or Router(config)#no tacacs-server administration Disabling DNS +------------ To disable DNS use the following command: Router(config)#no ip dns server Disabling RSVP +------------- To disable RSVP use the following commands: Router(config)#interface <Interface> Router(config)#no ip rsvp bandwidth Disabling L2F/L2TP +----------------- To disable L2F/L2TP use the following commands: Router(config)#clear vpdn tunnel l2tp all Router(config)#no vpdn-group <group-name> Router(config)#no vpdn enable Disabling IP SLA Responder +------------------------- To disable IP SLA Responder use the following command: Router(config)#no ip sla monitor responder Disabling MGCP +------------- To disable MGCP use the following command: Router(config)#no mgcp Disabling SIP +------------ To disable SIP use the following commands: Router(config)#sip-ua Router(config-sip-ua)#no transport udp Router(config-sip-ua)#no transport tcp If IPv4 UDP-based Services Are Required +--------------------------------------- By deploying IPv6 Access Control List (ACL) it is possible to prevent offending IPv6 packets reaching vulnerable UDP services. The ACL in the following example will block all IPv6 traffic from reaching vulnerable services. Router(config)#ipv6 access-list protect_IPv4_services Router(config-ipv6-acl)#deny udp any 2001:DB8:1:128::/64 eq tacacs Router(config-ipv6-acl)#deny udp any 2001:DB8:1:128::/64 eq domain Router(config-ipv6-acl)#deny udp any 2001:DB8:1:128::/64 eq 1698 Router(config-ipv6-acl)#deny udp any 2001:DB8:1:128::/64 eq 1701 Router(config-ipv6-acl)#deny udp any 2001:DB8:1:128::/64 eq 1967 Router(config-ipv6-acl)#deny udp any 2001:DB8:1:128::/64 eq 2427 Router(config-ipv6-acl)#deny udp any 2001:DB8:1:128::/64 eq 5060 !-- Permit/deny all other Layer 3 and Layer 4 traffic in accordance !-- with existing security policies and configurations ! !-- Allow all other IPv6 traffic Router(config-ipv6-acl)#permit ipv6 any 2001:db8:1:128::/64 ! ! Router(config)#interface FastEthernet0/1 Router(config-if)#ipv6 traffic-filter protect_IPv4_services in Additional mitigation techniques that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory: http://www.cisco.com/warp/public/707/cisco-amb-20080326-IPv4IPv6.shtml Obtaining Fixed Software ======================== Cisco has released free software updates that address this vulnerability.

Unspecified vulnerability in the Multicast Virtual Private Network (MVPN) implementation in Cisco IOS 12.0, 12.2, 12.3, and 12.4 allows remote attackers to create "extra multicast states on the core routers" via a crafted Multicast Distribution Tree (MDT) Data Join message. A vulnerability in the way Cisco IOS handles IPv6 packets could result in a remotely exploitable denial of service. Information gained could aid in further attacks. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released.

Please reference the following software table to find a release that fixes all published Security Advisories as of March 26th, 2008. * March 26th bundled IOS Advisory Table http://www.cisco.com/warp/public/707/cisco-sa-20080326-bundle.shtml Individual publication links are listed below: * Cisco IOS Virtual Private Dial-up Network Denial of Service Vulnerability http://www.cisco.com/warp/public/707/cisco-sa-20080326-pptp.shtml * Multiple DLSw Denial of Service Vulnerabilities in Cisco IOS http://www.cisco.com/warp/public/707/cisco-sa-20080326-dlsw.shtml * Cisco IOS User Datagram Protocol Delivery Issue For IPv4/IPv6 Dual-stack Routers http://www.cisco.com/warp/public/707/cisco-sa-20080326-IPv4IPv6.shtml * Vulnerability in Cisco IOS with OSPF, MPLS VPN, and Supervisor 32, Supervisor 720, or Route Switch Processor 720 http://www.cisco.com/warp/public/707/cisco-sa-20080326-queue.shtml * Cisco IOS Multicast Virtual Private Network (MVPN) Data Leak http://www.cisco.com/warp/public/707/cisco-sa-20080326-mvpn.shtml Affected Products ================= Vulnerable Products +------------------ Devices that run Cisco IOS and are configured for MVPN are affected. An IOS device that is configured for MVPN has a line that is similar to this in the running configuration example: mdt default <group-address> In order to determine the software that runs on a Cisco IOS product, log in to the device and issue the show version command to display the system banner. Cisco IOS\xae software identifies itself as "Internetwork Operating System Software" or simply "IOS." On the next line of output, the image name displays between parentheses, followed by "Version" and the Cisco IOS release name. Other Cisco devices do not have the "show version" command or give different output. The following example shows output from a device that runs an IOS image: Router>show version Cisco IOS Software, 7200 Software (C7200-IK9S-M), Version 12.3(14)T1, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2005 by Cisco Systems, Inc. Compiled Thu 31-Mar-05 08:04 by yiyan Additional information about Cisco IOS release naming is available at the following link: http://www.cisco.com/en/US/products/sw/iosswrel/ps1828/products_white_paper09186a008018305e.shtml. Products Confirmed Not Vulnerable +-------------------------------- No other Cisco products, including IOS XR software, are currently known to be affected by this vulnerability. Details ======= MVPN architecture introduces an additional set of protocols and procedures that help enable a service provider to support multicast traffic in an MPLS VPN. MVPN allows the transparent transport of IP multicast traffic across the MPLS VPN backbone of a provider and allows a service provider to offer multicast services to MPLS VPN customers. MDT Data Join messages can be sent in unicast or multicast. The vulnerability can also allow leaking multicast traffic from different MPLS VPNs. In order to successfully exploit this vulnerability, an attacker needs to know or guess the Border Gateway Protocol (BGP) peering IP address of a remote PE router and the address of the multicast group that is used in other MPLS VPNs. This vulnerability is documented in the Cisco Bug ID CSCsi01470 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2008-1156. Vulnerability Scoring Details ============================= Cisco has provided scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS Version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco has provided an FAQ to answer additional questions regarding CVSS at http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at http://intellishield.cisco.com/security/alertmanager/cvss CSCsi01470 - Crafted MDT Data Join TLV in VRF causes multicast state CVSS Base Score - 7.5 Access Vector: Network Access Complexity: Low Authentication: None Confidentiality Impact: Partial Integrity Impact: Partial Availability Impact: Partial CVSS Temporal Score - 6.2 Exploitability: Functional Remediation Level: Official-Fix Report Confidence: Confirmed Impact ====== Successful exploitation of the vulnerability can result in the creation of extra multicast states on the core routers or the leaking of multicast traffic from one MPLS VPN to another. Software Versions and Fixes =========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center (TAC) or your contracted maintenance provider for assistance. Each row of the Cisco IOS software table (below) names a Cisco IOS release train. If a given release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table. +----------------------------------------+ | Major | Availability of Repaired | | Release | Releases | |------------+---------------------------| | Affected | First Fixed | Recommended | | 12.0-Based | Release | Release | | Releases | | | |------------+-------------+-------------| | 12.0 | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0DA | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0DB | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0DC | Not | | | | Vulnerable | | |------------+-------------+-------------| | | 12.0(32)S9 | | | 12.0S | | 12.0(32)S10 | | | 12.0(33)S | | |------------+-------------+-------------| | 12.0SC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SL | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SP | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0ST | Not | | | | Vulnerable | | |------------+-------------+-------------| | | Vulnerable;

The workarounds need to be applied on all Virtual Routing and Forwarding (VRF) interfaces of all PE routers. Otherwise, attackers can target remote PE routers and can still exploit this vulnerability. Even if only one PE router in the network runs an unfixed version of IOS code, it is vulnerable to packets that come from systems that are connected to remote PE routers. In such a case, workarounds need to be deployed on all PE routers to successfully mitigate this vulnerability. The "mdt data <group> <mask>" or "mdt data <group> <mask> threshold <n> list <acl>" commands do not mitigate this vulnerability. Filtering Packets to UDP Port 3232 +--------------------------------- MDT Data Join messages are sent to UDP port 3232. Creating an access-list that filters destination UDP port 3232 and applying it on the VRF interface of the PE router mitigates this vulnerability. Such an access-list looks like this: access-list 100 deny udp any any eq 3232 access-list 100 permit ip any any interface Serial 0/0 ip vrf forwarding <vpn-1> ... ip access-group 100 in Note that this access-list can also filter legitimate traffic that is destined to UDP port 3232. In such a case, the access-list can be modified to be more specific by providing individual BGP peer IP addresses. This is explained in the section that follows. Filtering BGP Peer IP Addresses on the VRF Interface +--------------------------------------------------- In order to successfully exploit this vulnerability, an attacker needs to send MDT Data Join messages by spoofing the packets from the IP address of one of the existing iBGP peers. Because MDT Data Join messages are only used between PE routers, the packets from CE devices can safely be filtered. Creating an access-list that filters iBGP peer IP addresses as source addresses and applying it on the VRF interface of the PE router mitigates this vulnerability. The access-list needs to filter all iBGP peer IP addresses. Such an access-list looks like this example: access-list 100 deny udp host <ibgp-peer-1> any eq 3232 access-list 100 deny udp host <ibgp-peer-2> any eq 3232 ... access-list 100 deny udp host <ibgp-peer-n> any eq 3232 access-list 100 permit ip any any interface Serial 0/0 ip vrf forwarding <vpn-1> ... ip access-group 100 in Additional mitigation techniques that can be deployed on Cisco devices within the network are available in the Cisco Applied Mitigation Bulletin companion document for this advisory: http://www.cisco.com/warp/public/707/cisco-amb-20080326-mvpn.shtml Obtaining Fixed Software ======================== Cisco has released free software updates that address this vulnerability.

Memory leak in the virtual private dial-up network (VPDN) component in Cisco IOS before 12.3 allows remote attackers to cause a denial of service (memory consumption) via a series of PPTP sessions, related to "dead memory" that remains allocated after process termination, aka bug ID CSCsj58566. A vulnerability in the way Cisco IOS handles IPv6 packets could result in a remotely exploitable denial of service. (DoS) Vulnerabilities exist.Service disruption by a third party (DoS) There is a possibility of being put into a state. Cisco IOS is prone to multiple denial-of-service vulnerabilities that occur in the virtual private dial-up (VPDN) when the Point-to-Point Tunneling Protocol (PPTP) is enabled. Successfully exploiting these issues may cause a memory leak or prevent the establishment of VPDN connections, denying service to legitimate users. ---------------------------------------------------------------------- A new version (0.9.0.0 - Release Candidate 1) of the free Secunia PSI has been released. The new version includes many new and advanced features, which makes it even easier to stay patched. 3) Some errors exist in the Data-Link-Switching (DLSw) feature when processing UDP and IP protocol 91 packets. 4) An error exists in the processing of IPv6 packets, which can be exploited to prevent the interface from receiving additional traffic or to cause the device to crash (if RSVP service is configured on the interface) by sending a specially crafted IPv6 packet to the device. Successful exploitation of this vulnerability requires that IPv6 and certain IPv4 UDP services are enabled. 5) An error exists in the implementation of Multicast Virtual Private Networks (MVPN), which can be exploited to create extra multicast states on the core routers via specially crafted Multicast Distribution Tree (MDT) Data Join messages. This can also be exploited to receive multicast traffic from VPNs that are not connected to the same Provider Edge (PE). Successful exploitation of the multicast traffic leak requires that the attacker knows or guesses the Border Gateway Protocol (BGP) peering IP address of a remote PE router and the address of the multicast group that is used in other MPLS VPNs. SOLUTION: Update to the fixed version (please see the vendor's advisories for details). 5) The vendor credits Thomas Morin.

PPTP is only one of the supported tunneling protocols used to tunnel PPP frames within the VPDN solution. The first vulnerability is a memory leak that occurs as a result of PPTP session termination. The second vulnerability may consume all interface descriptor blocks on the affected device because those devices will not reuse virtual access interfaces. If these vulnerabilities are repeatedly exploited, the memory and/or interface resources of the attacked device may be depleted. Cisco has made free software available to address these vulnerabilities for affected customers. There are no workarounds available to mitigate the effects of these vulnerabilities. This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20080326-pptp.shtml Note: The March 26, 2008 publication includes five security advisories. The advisories all address vulnerabilities in Cisco's Internetwork Operating System (IOS) software. Each advisory lists the releases that correct the vulnerability described in the advisory, and also lists the releases that correct the vulnerabilities in the other five advisories. Please reference the following software table to find a release that fixes all published software advisories as of March 26th, 2008: * March 26th Bundled IOS Advisory Table http://www.cisco.com/warp/public/707/cisco-sa-20080326-bundle.shtml Individual publication links are listed below: * Cisco IOS Virtual Private Dial-up Network Denial of Service Vulnerability http://www.cisco.com/warp/public/707/cisco-sa-20080326-pptp.shtml * Multiple DLSw Denial of Service Vulnerabilities in Cisco IOS http://www.cisco.com/warp/public/707/cisco-sa-20080326-dlsw.shtml * Cisco IOS User Datagram Protocol Delivery Issue For IPv4/IPv6 Dual-stack Routers http://www.cisco.com/warp/public/707/cisco-sa-20080326-IPv4IPv6.shtml * Vulnerability in Cisco IOS with OSPF, MPLS VPN, and Supervisor 32, Supervisor 720, or Route Switch Processor 720 http://www.cisco.com/warp/public/707/cisco-sa-20080326-queue.shtml * Cisco IOS Multicast Virtual Private Network (MVPN) Data Leak http://www.cisco.com/warp/public/707/cisco-sa-20080326-mvpn.shtml Affected Products ================= Devices that are running certain Cisco IOS versions prior to 12.3 with VPDN enabled may be affected by these vulnerabilities. Vulnerable Products +------------------ Devices that are running affected versions of Cisco IOS with VPDN enabled and are configured to accept termination of PPTP sessions are vulnerable. To determine whether VPDN is enabled on your device, log in to the device and issue the command-line interface (CLI) command "show running-config". If the output contains "vpdn enable" along with a "vpdn-group <name>" command, VPDN is enabled on the device. The device will accept termination of PPTP sessions if the command "protocol any" or "protocol pptp" is defined under the "vpdn-group <name>" command. The following example shows a device that is running VPDN and will accept termination of PPTP sessions: Router#show running-config Building configuration... ! !--- Output truncated. ! vpdn enable ! vpdn-group test_only ! Default PPTP VPDN group accept-dialin protocol pptp virtual-template 1 ! !---Remaining output truncated. To determine the software version running on a Cisco product, log in to the device and issue the "show version" command to display the system banner. Cisco IOS software will identify itself as "Internetwork Operating System Software" or simply "IOS." On the next line of output, the image name will be displayed between parentheses, followed by "Version" and the IOS release name. Other Cisco devices will not have the "show version" command or will give different output. The following example identifies a Cisco product that is running Cisco IOS release 12.2(7): Cisco Internetwork Operating System Software IOS (tm) 7200 Software (C7200-IS-M), Version 12.2(7), RELEASE SOFTWARE (fc1) Copyright (c) 1986-2002 by cisco Systems, Inc. Compiled Tue 15-Jan-02 18:31 by pwade Image text-base: 0x600089C0, data-base: 0x613A6000 Additional information about Cisco IOS release naming can be found at http://www.cisco.com/warp/public/620/1.html. Products Confirmed Not Vulnerable +-------------------------------- Devices that are running Cisco IOS versions 12.3 and later are not affected by these vulnerabilities. Devices that are explicitly configured for VPDN protocols other than PPTP are not affected. Devices that are running Cisco IOS versions prior to 12.3 and do not have VPDN enabled are not affected by these vulnerabilities. Cisco IOS XR is not affected by these vulnerabilities. Details ======= VPDNs securely carry private data over a public network, allowing remote users to access a private network over a shared infrastructure such as the Internet. VPDNs maintain the same security and management policies as a private network, while providing a cost-effective method for point-to-point connections between remote users and a central network. PPTP is a network protocol that enables the secure transfer of data from a remote client to a private enterprise server by creating a VPDN across TCP/IP-based data networks. PPTP supports on-demand, multiprotocol, virtual private networking over public networks, such as the Internet. Details regarding the two known vulnerabilities in Cisco IOS devices that are running affected versions of system software follow: * Memory Leak due to PPTP Session Termination Upon completion of a PPTP session, memory is leaked from the processor memory on the terminating device. This is shown in the output of "show process memory" under the *Dead* process. The *Dead* process is not a real process. Its function is to account for the memory that is allocated under the context of another process which has terminated, in this case PPTP. When the administrator is logged into the device, if the device is under exploitation, the Holding entry of the *Dead* process under the "show process memory" command will be increasing. Following is an example showing a device that is holding *Dead* memory: Router#show process memory Total: 199718560, Used: 11147828, Free: 188570732 PID TTY Allocated Freed Holding Getbufs Retbufs Process 0 0 99812 1848 8415816 0 0 *Init* 0 0 444 778840 444 0 0 *Sched* 0 0 17481700 4930848 819672 180908 0 *Dead* 1 0 284 284 3828 0 0 Load Meter !--- Output truncated. The CLI command "show memory dead" allows administrators to examine the contents of *Dead*. The output will display many occurrences of PPTP in the output if the PPTP process is causing the leak.

This vulnerability is documented in Cisco bug ID CSCsj58566 and Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-1151 has been assigned to this vulnerability. * Virtual Access Interfaces Are Not Re-used Upon completion of a PPTP session, affected devices do not remove the virtual access interface that is associated with the PPTP session and do not reuse the interfaces in any future connections. This situation can result in an exhaustion of the interface descriptor block (IDB) limit, which will prevent any new interfaces being created within Cisco IOS, effectively blocking all new VPDN connections, even though the router may still have enough processor memory to remain up and running. A reload of the device is required to remove the interfaces. An IDB is a Cisco IOS internal data structure that contains information such as the IP address, interface state, and packet statistics. Cisco IOS software maintains one IDB for each interface present on a platform and one IDB for each subinterface. Further documentation on Cisco IOS IDBs can be found at: http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_tech_note09186a0080094322.shtml This vulnerability is documented in Cisco bug ID CSCdv59309 and Common Vulnerabilities and Exposures (CVE) identifier CVE-2008-1150 has been assigned to this vulnerability. Vulnerability Scoring Details ============================= Cisco is providing scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this Security Advisory is done in accordance with CVSS version 2.0. Cisco will provide a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. CVSS is a standards based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided an FAQ to answer additional questions regarding CVSS at http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at http://intellishield.cisco.com/security/alertmanager/cvss CSCsj58566 - Memory Leak due to PPTP Session Termination CVSS Base Score - 7.1 Access Vector: Network Access Complexity: Medium Authentication: None Confidentiality Impact: None Integrity Impact: None Availability Impact: Complete CVSS Temporal Score - 5.9 Exploitability: Functional Remediation Level: Official-Fix Report Confidence: Confirmed CSCdv59309 - Virtual Access Interfaces Are Not Re-used CVSS Base Score - 4.3 Access Vector: Network Access Complexity: Medium Authentication: None Confidentiality Impact: None Integrity Impact: None Availability Impact: Partial CVSS Temporal Score - 3.6 Exploitability: Functional Remediation Level: Official-Fix Report Confidence: Confirmed Impact ====== Successful exploitation of the vulnerability may result in a memory leak of processor memory or consumption of all available IDBs on the device. With continued exploitation, the device will deplete its processor memory or reach an IDB limit. Both impacts would result in a denial of service condition for the device. Software Versions and Fixes =========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center ("TAC") or your contracted maintenance provider for assistance. Each row of the Cisco IOS software table (below) names a Cisco IOS release train. If a given release train is vulnerable, then the earliest possible releases that contain the fix (along with the anticipated date of availability for each, if applicable) are listed in the "First Fixed Release" column of the table. The "Recommended Release" column indicates the releases which have fixes for all the published vulnerabilities at the time of this Advisory. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. Cisco recommends upgrading to a release equal to or later than the release in the "Recommended Releases" column of the table. +----------------------------------------+ | Major | Availability of Repaired | | Release | Releases | |------------+---------------------------| | Affected | First Fixed | Recommended | | 12.0-Based | Release | Release | | Releases | | | |------------+-------------+-------------| | 12.0 | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0DA | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0DB | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0DC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0S | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SL | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SP | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0ST | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SX | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SY | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0SZ | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0T | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0W | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0WC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0WT | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0XA | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0XB | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0XC | Not | | | | Vulnerable | | |------------+-------------+-------------| | 12.0XD | Not | | | | Vulnerable | | |------------+-------------+-------------| | | Releases | | | | prior to | | | | 12.0(7)XE2 | | | | are | | | 12.0XE | vulnerable, | | | | release | | | | 12.0(7)XE2 | | | | and later | | | | are not | | | | vulnerable;

Cisco recommends upgrading to the fixed version of Cisco IOS. Obtaining Fixed Software ======================== Cisco will make free software available to address this vulnerability for affected customers. This advisory will be updated as fixed software becomes available. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment. Customers may only install and expect support for the feature sets they have purchased. By installing, downloading, accessing or otherwise using such software upgrades, customers agree to be bound by the terms of Cisco's software license terms found at http://www.cisco.com/public/sw-license-agreement.html or as otherwise set forth at Cisco.com Downloads at http://www.cisco.com/public/sw-center/sw-usingswc.shtml. Do not contact either "psirt@cisco.com" or "security-alert@cisco.com" for software upgrades. Customers with Service Contracts +------------------------------- Customers with contracts should obtain upgraded software through their regular update channels. For most customers, this means that upgrades should be obtained through the Software Center on Cisco's worldwide website at http://www.cisco.com. Customers using Third Party Support Organizations +------------------------------------------------ Customers whose Cisco products are provided or maintained through prior or existing agreement with third-party support organizations such as Cisco Partners, authorized resellers, or service providers should contact that support organization for guidance and assistance with the appropriate course of action in regards to this advisory. The effectiveness of any workaround or fix is dependent on specific customer situations such as product mix, network topology, traffic behavior, and organizational mission. Due to the variety of affected products and releases, customers should consult with their service provider or support organization to ensure any applied workaround or fix is the most appropriate for use in the intended network before it is deployed. Customers without Service Contracts +---------------------------------- Customers who purchase direct from Cisco but who do not hold a Cisco service contract and customers who purchase through third-party vendors but are unsuccessful at obtaining fixed software through their point of sale should get their upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC contacts are as follows. * +1 800 553 2447 (toll free from within North America) * +1 408 526 7209 (toll call from anywhere in the world) * e-mail: tac@cisco.com Have your product serial number available and give the URL of this notice as evidence of your entitlement to a free upgrade.
