A specially crafted ZIP file, created by concatenating the contents of a clean TAR archive and a virus-infected ZIP archive, is parsed incorrectly and evades detection. If the length field in the header of a file with test EICAR virus included into a TAR archive is set to be greater than the archive's total length (1,000,000+original length in our experiments), the antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program. A Windows Compiled HTML Help (CHM) file is a set of HTML files, scripts, and images compressed using the LZX algorithm. For faster random accesses, the algorithm is reset at intervals instead of compressing the entire file as a single stream. The length of each interval is specified in the LZXC header. If an infected CHM file's header modified so that the reset interval is lower than in the original file, the antivirus declares the file to be clean. But the Windows CHM viewer hh.exe correctly decompresses the infected content located before the tampered header. Affected products - ClamAV 0.96.4, Sophos 4.61.0 CVE no - CVE-2012-1458 41. In a POSIX TAR archive, each member file has a 512-byte header protected by a simple checksum. Every header also contains a file length field, which is used by the extractor to locate the next header in the archive. If a TAR archive contains two files: the first one is clean, while the second is infected with test EICAR virus - and it is modified such that the length field in the header of the first, clean file to point into the middle of the header of the second, infected file. The antivirus declares the file to be clean but virus gets extracted correctly by the GNU tar program. If an infected tar.gz archive is appended 6 random bytes at the end, the antivirus declares the file to be clean but virus gets extracted by the gunzip+tar programs correctly by ignoring these bytes. GZIP files can contain multiple compressed streams, which are assembled when the contents are extracted. If an infected .tar.gz file is broken into two streams, the antivirus declares the infected .tar.gz file to be clean while tar+gunzip extract the virus correctly Affected products - AVG 10.0.0.1190, BitDefender 7.2, Command 5.2.11.5, Emsisoft 5.1.0.1, F-Secure 9.0.16160.0, Fortinent 4.2.254.0, Ikarus T3.1.1.97.0, Jiangmin 13.0.900, K7AntiVirus 9.77.3565, Kaspersky 7.0.0.125, McAfee 5.400.0.1158, McAfee-GW-Edition 2010.1C, NOD32 5795, Norman 6.06.12, Rising 22.83.00.03, Sophos 4.61.0, Symantec 20101.3.0.103, TrendMicro 9.120.0.1004, TrendMicro-HouseCall 9.120.0.1004, VBA32 3.12.14.2 CVE no - CVE-2012-1461 44.

The ELF file parser in eSafe 7.0.17.0, Rising Antivirus 22.83.00.03, Fortinet Antivirus 4.2.254.0, and Panda Antivirus 10.0.2.7 allows remote attackers to bypass malware detection via an ELF file with a modified abi field. NOTE: this may later be SPLIT into multiple CVEs if additional information is published showing that the error occurred independently in different ELF parser implementations. Successful exploits will allow attackers to bypass on-demand virus scanning, possibly allowing malicious files to escape detection.

The Quantum Scalar i500 and Dell ML6000 tape libraries contain the following WEB interface vulnerabilities: (1) The WEB interface allows unauthenticated remote users to view any file on the WEB server, such as http://device/logShow.htm?file=/etc/shadow . (2) http://device/checkQKMProg.htm There is a cross-site scripting vulnerability that allows you to get the session ID. (3) The POST parameter executes any command with the ROOT user. An information-disclosure vulnerability 2. A cross-site request-forgery vulnerability 4. A security-bypass vulnerability An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may let the attacker steal cookie-based authentication credentials and launch other attacks. The information-disclosure vulnerability can allow the attacker to obtain sensitive information that may aid in launching further attacks. Exploiting the cross-site request-forgery may allow a remote attacker to perform certain administrative actions and gain unauthorized access to the affected application. Other attacks are also possible. Attackers can exploit a password weakness issue to bypass security restrictions to obtain sensitive information or perform unauthorized actions; this may aid in launching further attacks. ---------------------------------------------------------------------- Become a PSI 3.0 beta tester!

Buffer overflow in the OSPFv2 implementation in ospfd in Quagga before 0.99.20.1 allows remote attackers to cause a denial of service (daemon crash) via a Link State Update (aka LS Update) packet containing a network-LSA link-state advertisement for which the data-structure length is smaller than the value in the Length header field. Quagga, a routing software suite, contains multiple vulnerabilities that result in a denial-of-service condition. Quagga is prone to multiple remote security vulnerabilities including: 1. A denial-of-service vulnerability 2. Multiple buffer-overflow vulnerabilities An attackers can exploit these issues to execute arbitrary code in the context of the application or cause denial-of-service conditions. Quagga versions prior to 0.99.20.1 are vulnerable. ============================================================================ Ubuntu Security Notice USN-1441-1 May 15, 2012 quagga vulnerabilities ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.04 LTS Summary: Quagga could be made to crash if it received specially crafted network traffic.

Summary: Updated quagga packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. The Quagga bgpd daemon implements the BGP (Border Gateway Protocol) routing protocol. The Quagga ospfd and ospf6d daemons implement the OSPF (Open Shortest Path First) routing protocol. A heap-based buffer overflow flaw was found in the way the bgpd daemon processed malformed Extended Communities path attributes. An attacker could send a specially-crafted BGP message, causing bgpd on a target system to crash or, possibly, execute arbitrary code with the privileges of the user running bgpd. The UPDATE message would have to arrive from an explicitly configured BGP peer, but could have originated elsewhere in the BGP network. (CVE-2011-3327) A stack-based buffer overflow flaw was found in the way the ospf6d daemon processed malformed Link State Update packets. An OSPF router could use this flaw to crash ospf6d on an adjacent router. (CVE-2011-3323) A flaw was found in the way the ospf6d daemon processed malformed link state advertisements. An OSPF neighbor could use this flaw to crash ospf6d on a target system. (CVE-2011-3324) A flaw was found in the way the ospfd daemon processed malformed Hello packets. An OSPF neighbor could use this flaw to crash ospfd on a target system. (CVE-2011-3325) A flaw was found in the way the ospfd daemon processed malformed link state advertisements. An OSPF router in the autonomous system could use this flaw to crash ospfd on a target system. (CVE-2011-3326) An assertion failure was found in the way the ospfd daemon processed certain Link State Update packets. An OSPF router could use this flaw to cause ospfd on an adjacent router to abort. (CVE-2012-0249) A buffer overflow flaw was found in the way the ospfd daemon processed certain Link State Update packets. An OSPF router could use this flaw to crash ospfd on an adjacent router. (CVE-2012-0250) Two flaws were found in the way the bgpd daemon processed certain BGP OPEN messages. A configured BGP peer could cause bgpd on a target system to abort via a specially-crafted BGP OPEN message.

The Linux kernel before 3.3.1, when KVM is used, allows guest OS users to cause a denial of service (host OS crash) by leveraging administrative access to the guest OS, related to the pmd_none_or_clear_bad function and page faults for huge pages. Cross scripting and preconfigured password vulnerabilities have been reported to exist in the Quantum Scalar i500, Dell ML6000 and IBM TS3310 tape libraries. The Linux kernel is prone to a local denial-of-service vulnerability. Attackers can exploit this issue to cause the kernel to crash, denying service to legitimate users. Linux Kernel 2.6.x is vulnerable. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: kernel security and bug fix update Advisory ID: RHSA-2012:0743-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0743.html Issue date: 2012-06-18 CVE Names: CVE-2012-0044 CVE-2012-1179 CVE-2012-2119 CVE-2012-2121 CVE-2012-2123 CVE-2012-2136 CVE-2012-2137 CVE-2012-2372 CVE-2012-2373 ===================================================================== 1. Summary: Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - noarch, x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. This update fixes the following security issues: * A local, unprivileged user could use an integer overflow flaw in drm_mode_dirtyfb_ioctl() to cause a denial of service or escalate their privileges. (CVE-2012-0044, Important) * A buffer overflow flaw was found in the macvtap device driver, used for creating a bridged network between the guest and the host in KVM (Kernel-based Virtual Machine) environments. A privileged guest user in a KVM guest could use this flaw to crash the host. Note: This issue only affected hosts that have the vhost_net module loaded with the experimental_zcopytx module option enabled (it is not enabled by default), and that also have macvtap configured for at least one guest. (CVE-2012-2119, Important) * When a set user ID (setuid) application is executed, certain personality flags for controlling the application's behavior are cleared (that is, a privileged application will not be affected by those flags). It was found that those flags were not cleared if the application was made privileged via file system capabilities. A local, unprivileged user could use this flaw to change the behavior of such applications, allowing them to bypass intended restrictions. Note that for default installations, no application shipped by Red Hat for Red Hat Enterprise Linux is made privileged via file system capabilities. (CVE-2012-2123, Important) * It was found that the data_len parameter of the sock_alloc_send_pskb() function in the Linux kernel's networking implementation was not validated before use. A privileged guest user in a KVM guest could use this flaw to crash the host or, possibly, escalate their privileges on the host. (CVE-2012-2136, Important) * A buffer overflow flaw was found in the setup_routing_entry() function in the KVM subsystem of the Linux kernel in the way the Message Signaled Interrupts (MSI) routing entry was handled. A local, unprivileged user could use this flaw to cause a denial of service or, possibly, escalate their privileges. (CVE-2012-2137, Important) * A race condition was found in the Linux kernel's memory management subsystem in the way pmd_none_or_clear_bad(), when called with mmap_sem in read mode, and Transparent Huge Pages (THP) page faults interacted. A privileged user in a KVM guest with the ballooning functionality enabled could potentially use this flaw to crash the host. A local, unprivileged user could use this flaw to crash the system. (CVE-2012-1179, Moderate) * A flaw was found in the way device memory was handled during guest device removal. Upon successful device removal, memory used by the device was not properly unmapped from the corresponding IOMMU or properly released from the kernel, leading to a memory leak. A malicious user on a KVM host who has the ability to assign a device to a guest could use this flaw to crash the host. (CVE-2012-2121, Moderate) * A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2372, Moderate) * A race condition was found in the Linux kernel's memory management subsystem in the way pmd_populate() and pte_offset_map_lock() interacted on 32-bit x86 systems with more than 4GB of RAM. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2373, Moderate) Red Hat would like to thank Chen Haogang for reporting CVE-2012-0044. This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which contain backported patches to correct these issues, and fix the bugs noted in the Technical Notes. The system must be rebooted for this update to take effect. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system. 5.

(CVE-2012-0045) A flaw was discovered in the Linux kernel's cifs file system. (CVE-2012-1090) H. (CVE-2012-1097) A flaw was discovered in the Linux kernel's cgroups subset. (CVE-2012-1146) A flaw was found in the Linux kernel's handling of paged memory. (CVE-2012-1179) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 11.10: linux-image-3.0.0-19-generic 3.0.0-19.33 linux-image-3.0.0-19-generic-pae 3.0.0-19.33 linux-image-3.0.0-19-omap 3.0.0-19.33 linux-image-3.0.0-19-powerpc 3.0.0-19.33 linux-image-3.0.0-19-powerpc-smp 3.0.0-19.33 linux-image-3.0.0-19-powerpc64-smp 3.0.0-19.33 linux-image-3.0.0-19-server 3.0.0-19.33 linux-image-3.0.0-19-virtual 3.0.0-19.33 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well. (CVE-2011-4347, Moderate) * A flaw was found in the way the Linux kernel's XFS file system implementation handled on-disk Access Control Lists (ACLs). (CVE-2012-0038, Moderate) * It was found that the Linux kernel's register set (regset) common infrastructure implementation did not check if the required get and set handlers were initialized. Peter Anvin for reporting CVE-2012-1097. This update also fixes the following bugs: * When a RoCE (RDMA over Converged Ethernet) adapter with active RoCE communications was taken down suddenly (either by adapter failure or the intentional shutdown of the interface), the ongoing RoCE communications could cause the kernel to panic and render the machine unusable. A patch has been provided to protect the kernel in this situation and to pass an error up to the application still using the interface after it has been taken down instead. (BZ#799944) * The fix for Red Hat Bugzilla bug 713494, released via RHSA-2011:0928, introduced a regression. Attempting to change the state of certain features, such as GRO (Generic Receive Offload) or TSO (TCP segment offloading), for a 10 Gigabit Ethernet card that is being used in a virtual LAN (VLAN) resulted in a kernel panic. (BZ#816974) * If a new file was created on a Network File System version 4 (NFSv4) share, the ownership was set to nfsnobody (-2) until it was possible to upcall to the idmapper. As a consequence, subsequent file system operations could incorrectly use "-2" for the user and group IDs for the given file, causing certain operations to fail. In reported cases, this issue also caused "Viminfo file is not writable" errors for users running Vim with files on an NFSv4 share. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Note: the current version of the following document is available here: https://h20564.www2.hp.com/portal/site/hpsc/public/kb/ docDisplay?docId=emr_na-c04135307 SUPPORT COMMUNICATION - SECURITY BULLETIN Document ID: c04135307 Version: 1 HPSBGN02970 rev.1 - HP Rapid Deployment Pack (RDP) or HP Insight Control Server Deployment, Multiple Remote Vulnerabilities affecting Confidentiality, Integrity and Availability NOTICE: The information in this Security Bulletin should be acted upon as soon as possible.

Citrix Licensing is prone to a denial-of-service vulnerability. A remote attacker can leverage this issue to crash the affected application, denying service to legitimate users. Citrix Licensing 11.6.1 build 10007 is vulnerable; other versions may also be affected.

Use-after-free vulnerability in nginx before 1.0.14 and 1.1.x before 1.1.17 allows remote HTTP servers to obtain sensitive information from process memory via a crafted backend response, in conjunction with a client request. nginx is prone to an information-disclosure vulnerability. Attackers can exploit this issue to harvest sensitive information that may lead to further attacks. BUGTRAQ ID: 52578 CVE ID: CVE-2012-1180 nginx is a widely used high-performance web server. There is an information disclosure vulnerability in nginx's implementation of processing malformed HTTP responses from upstream servers. 0 nginx 1.0.9 nginx 1.0.8 nginx 1.0.10 Vendor patch: Igor Sysoev ----------- At present, the vendor has released an upgrade patch to fix this security problem, please go to the vendor's homepage to download: http ://nginx.net/. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201203-22 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - http://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: High Title: nginx: Multiple vulnerabilities Date: March 28, 2012 Bugs: #293785, #293786, #293788, #389319, #408367 ID: 201203-22 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in nginx, the worst of which may allow execution of arbitrary code. Background ========== nginx is a robust, small, and high performance HTTP and reverse proxy server. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/nginx < 1.0.14 >= 1.0.14 Description =========== Multiple vulnerabilities have been found in nginx: * The TLS protocol does not properly handle session renegotiation requests (CVE-2009-3555). * The "ngx_http_process_request_headers()" function in ngx_http_parse.c could cause a NULL pointer dereference (CVE-2009-3896). * nginx does not properly sanitize user input for the the WebDAV COPY or MOVE methods (CVE-2009-3898). * The "ngx_resolver_copy()" function in ngx_resolver.c contains a boundary error which could cause a heap-based buffer overflow (CVE-2011-4315). * nginx does not properly parse HTTP header responses which could expose sensitive information (CVE-2012-1180). Impact ====== A remote attacker could possibly execute arbitrary code with the privileges of the nginx process, cause a Denial of Service condition, create or overwrite arbitrary files, or obtain sensitive information. Workaround ========== There is no known workaround at this time. Resolution ========== All nginx users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/nginx-1.0.14" References ========== [ 1 ] CVE-2009-3555 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3555 [ 2 ] CVE-2009-3896 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3896 [ 3 ] CVE-2009-3898 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-3898 [ 4 ] CVE-2011-4315 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2011-4315 [ 5 ] CVE-2012-1180 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1180 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201203-22.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.

McAfee Email and Web Security (EWS) 5.x before 5.5 Patch 6 and 5.6 before Patch 3, and McAfee Email Gateway (MEG) 7.0 before Patch 1, allows remote authenticated users to reset the passwords of arbitrary administrative accounts via unspecified vectors. A remote attacker could leverage the cross-site scripting issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and launch other attacks. Exploiting the information-disclosure issues allow the attacker to view local files within the context of the Web server process. Exploiting the security-bypass vulnerability allows attackers to bypass security restrictions and obtain sensitive information or perform unauthorized actions. Exploiting the directory-traversal issue allows attackers to use directory-traversal strings to retrieve arbitrary files in the context of the affected application. Exploiting the insecure-encryption issue allows attackers to determine encryption keys, which may lead to further attacks. The solution offers incoming threat protection, outgoing encryption, data loss prevention, and more. ---------------------------------------------------------------------- Become a PSI 3.0 beta tester!

Microsoft Windows-based systems that are running Internet Explorer or another browser that supports Microsoft ActiveX technology may be affected if the system has ever connected to a device that is running the Cisco Clientless VPN solution. The affected ActiveX control is distributed to endpoint systems by Cisco ASA. However, the impact of successful exploitation of this vulnerability is to the endpoint system only and does not compromise Cisco ASA devices. Cisco has released free software updates that address this vulnerability. Workarounds that mitigate this vulnerability are available. Customers who are using Cisco ASA Software version 7.0 or 7.1 should contact their Cisco support team for assistance in upgrading to a supported version of Cisco ASA Software. Note: The affected implementation of the Cisco Clientless VPN solution was introduced with the release of Cisco ASA Software version 7.1. This issue does not affect devices running Cisco PIX Software. Administrators may determine whether the Cisco Clientless VPN solution is enabled on their devices by issuing the "show running-config webvpn" command. The following example shows the response when the Cisco Clientless VPN solution is enabled: ciscoasa# show running-config webvpn webvpn enable outside End user systems running Microsoft Windows may be affected if they have used the Cisco Clientless VPN feature on an affected device from a browser that supports ActiveX technology. Devices that contain the cscopf.ocx ActiveX control registered with a class ID (CLSID) of {B8E73359-3422-4384-8D27-4EA1B4C01232} are affected. The affected controls are marked both Safe for Scripting (SFS) and Safe for Initialization (SFI), which may present additional attack vectors when a system has registered and cached the affected control. The Cisco Clientless VPN feature allows users to use a web browser to create an SSL VPN tunnel from an endpoint device to a Cisco ASA device. When connected, the ASA pushes several ActiveX and Java applications to the endpoint device to allow a number of features to operate. The attacker-supplied code would be executed with the privileges of the user who invoked the browser used to visit the attacker-controlled website. If the user has administrative privileges, a complete compromise may occur. Affected endpoint systems will need to disable the control via one of the methods suggested in the "Workarounds" section of this document. When loaded on an endpoint system, the affected control has a binary name of cscopf.ocx and is registered on a system with a CLSID of {B8E73359-3422-4384-8D27-4EA1B4C01232}. Fixed versions of the cscopf.ocx control are registered with CLSID {C861B75F-EE32-4aa4-B610-281AF26A8D1C}. Cisco is requesting that Microsoft set a global kill bit for this control in a future Microsoft kill-bit update. After this update occurs, the affected control will stop operating on all affected endpoint systems that load the Microsoft-provided update. This issue is documented in Cisco bug ID CSCtr00165 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2012-0358. Vulnerability Scoring Details ============================= Cisco has scored the vulnerability in this advisory based on the Common Vulnerability Scoring System (CVSS). The CVSS scoring in this security advisory is in accordance with CVSS version 2.0. CVSS is a standards-based scoring method that conveys vulnerability severity and helps organizations determine the urgency and priority of a response. Cisco has provided a base and temporal score. Customers can also compute environmental scores that help determine the impact of the vulnerability in their own networks. Cisco has provided additional information regarding CVSS at the following link: http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to compute the environmental impact for individual networks at the following link: http://intellishield.cisco.com/security/alertmanager/cvss * CSCtr00165 ("Cisco Clientless VPN Port Forwarder ActiveX Control Remote Code Execution Vulnerability") CVSS Base Score - 9.3 Access Vector - Network Access Complexity - Medium Authentication - None Confidentiality Impact - Complete Integrity Impact - Complete Availability Impact - Complete CVSS Temporal Score - 7.7 Exploitability - Functional Remediation Level - Official-Fix Report Confidence - Confirmed Impact ====== Successful exploitation of the vulnerability may allow a remote, unauthenticated attacker to execute arbitrary code on the affected end-user system with the privileges of the user who invoked the web browser. If the user has administrative privileges, code execution may result in a complete compromise of the affected system. Software Versions and Fixes =========================== When considering software upgrades, customers are advised to consult the Cisco Security Advisories and Responses archive at http://www.cisco.com/go/psirt and review subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers. +---------------------------------------------------------------+ |Affected | First Fixed | Recommended Release | |Version |Release | | |--------------+-----------------+------------------------------| |Cisco ASA 7.0 |Not Vulnerable |Migrate to 7.2 or later | |--------------+-----------------+------------------------------| |Cisco ASA 7.1 |Vulnerable |Vulnerable; Migrate to 7.2 or | | | |later | |--------------+-----------------+------------------------------| |Cisco ASA 7.2 | 7.2(5.6) |7.2(5.7) | |--------------+-----------------+------------------------------| |Cisco ASA 8.0 |8.0(5.26) |Migrate to 8.2(5.26) or later | |--------------+-----------------+------------------------------| |Cisco ASA 8.1 | 8.1(2.53) |Migrate to 8.2(5.26) or later | |--------------+-----------------+------------------------------| |Cisco ASA 8.2 | 8.2(5.18) |8.2(5.26) | |--------------+-----------------+------------------------------| |Cisco ASA 8.3 | 8.3(2.28) |Migrate to 8.4(3.8) or later | |--------------+-----------------+------------------------------| |Cisco ASA 8.4 |8.4(2.16) |8.4(3.8) | |--------------+-----------------+------------------------------| |Cisco ASA 8.5 |Not Vulnerable |8.5(1.7) | |--------------+-----------------+------------------------------| |Cisco ASA 8.6 |8.6(1.1) |8.6(1.1) | +---------------------------------------------------------------+ Note: Cisco ASA Software version 7.0 and 7.1 have reached end of software maintenance. Customers who are using Cisco ASA Software version 7.0 or 7.1 should contact their Cisco support team for assistance in upgrading to a supported version of Cisco ASA Software. Note: The recommended releases contain the fixes for all vulnerabilities for all the advisories published in the publication. Cisco recommends upgrading to a release that is equal to or later than these recommended releases. Affected endpoint systems will need to download the fixed version by connecting to a Cisco ASA device that is running fixed software via the Cisco Clientless Web solution or disable the affected control via one of the methods mentioned in the "Workarounds" section of this document. Workarounds =========== End users or administrators may mitigate Internet Explorer as an attack vector by setting the kill bit for the affected ActiveX control. This can be achieved by modifying the registry either directly on the affected machine or via an Active Directory Group Policy. Warning: Incorrectly modifying the system registry of a Microsoft Windows-based device may cause serious problems. Neither Cisco nor Microsoft can guarantee that you can resolve problems that may result from improper registry modification from either applying the registry changes via a .reg file or by using the Registry Editor incorrectly. Modify the registry of your system at your own risk. To set the kill bit for the CLSID with a value of {B8E73359-3422-4384-8D27-4EA1B4C01232}, paste the following text in a text editor such as Notepad. Save the file using the .reg filename extension. Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{B8E73359-3422-4384-8D27-4EA1B4C01232}] "Compatibility Flags"=dword:04000400 [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\ActiveX Compatibility\{B8E73359-3422-4384-8D27-4EA1B4C01232}] "Compatibility Flags"=dword:04000400 End users can apply this .reg file to individual systems by double-clicking the file. Administrators can also apply the registry change across domains by using Group Policy. You can find more information about using Group Policy in the following Microsoft TechNet article: Group Policy Collection When the registry change has been applied, Microsoft Internet Explorer must be restarted for the changes to take effect. Once the kill bit has been set, the affected control will no longer be accessible by the Cisco Clientless VPN system or a malicious web page when accessed by Internet Explorer. One common component that may stop operating is the ActiveX RDP plug-in. Mitigations that can be deployed on Cisco devices in a network are available in the Cisco Applied Intelligence companion document for this advisory: http://tools.cisco.com/security/center/content/CiscoAppliedMitigationBulletin/cisco-amb-20120314-asaclient Obtaining Fixed Software ======================== Cisco has released free software updates that address the vulnerability described in this advisory.

Cisco has released free software updates that address these vulnerabilities. Workarounds are available to mitigate some of the vulnerabilities. A separate Cisco Security Advisory has been published to disclose the vulnerabilities that affect the Cisco FWSM. Affected versions of Cisco ASA Software will vary depending on the specific vulnerability. Consult the "Software Versions and Fixes" section of this security advisory for more information about the affected version. Cisco PIX has reached end of maintenance support. Consult the dedicated section for Cisco PIX Security Appliances in the "Vulnerable Products" section of this security advisory for more information about affected versions. Vulnerable Products +------------------ For specific version information, refer to the "Software Versions and Fixes" section of this advisory. Cisco ASA UDP Inspection Engine Denial of Service Vulnerability +-------------------------------------------------------------- The Cisco ASA UDP inspection engine that is used to inspect UDP-based protocols contains a vulnerability that could allow a remote unauthenticated attacker to trigger a reload of the Cisco ASA. All UDP protocols that are being inspected by the Cisco ASA UDP inspection engine may be vulnerable. The following protocols are known to use the Cisco ASA UDP inspection engine: * Domain Name System (DNS) * Session Initiation Protocol (SIP) * Simple Network Management Protocol (SNMP) * GPRS Tunneling Protocol (GTP) * H.323, H.225 RAS * Media Gateway Control Protocol (MGCP) * SunRPC * Trivial File Transfer Protocol (TFTP) * X Display Manager Control Protocol (XDMCP) * IBM NetBios * Instant Messaging (depending on the particular IM client/solution being used) Note: UDP inspection engines may be enabled by default on Cisco ASA Software. Please consult your user guide for more information. The default inspected ports are listed at the following link: http://www.cisco.com/en/US/docs/security/asa/asa84/configuration/guide/inspect_overview.html Note: The Cisco ASA UDP inspection can be applied to non-default UDP ports via class-map and policy-map commands. Any instance of use of the Cisco ASA UDP inspection engines may be vulnerable to this vulnerability, thus, configurations that include non-default UDP ports but use the Cisco ASA UDP inspection engine are considered vulnerable. To determine whether any of the above inspections are enabled, issue the show service-policy | include <inspection engine name> command and confirm that the command returns output. The following example shows a Cisco ASA configured to inspect IBM NetBIOS traffic: ciscoasa# show service-policy | include netbios Inspect: netbios, packet 0, drop 0, reset-drop 0 Cisco ASA Threat Detection Denial of Service Vulnerability +--------------------------------------------------------- The Cisco ASA Threat Detection feature, when configured with the Scanning Threat Mode feature and with shun option enabled, contains a vulnerability that could allow a remote unauthenticated attacker to trigger a reload of the Cisco ASA. This feature is not enabled by default. To determine whether the Cisco ASA Threat Detection with Scanning Threat feature and shun option is enabled, issue the show running-config threat-detection scanning-threat command and confirm that the returned output includes the shun option. The following example shows a vulnerable configuration: ciscoasa# show running-config threat-detection scanning-threat threat-detection scanning-threat shun Note: This feature was first introduced in Cisco ASA Software Version 8.0(2), Previous versions of Cisco ASA are not vulnerable. Cisco ASA Syslog Message 305006 Denial of Service Vulnerability +-------------------------------------------------------------- A denial of service (DoS) vulnerability exists in the implementation of one specific system log (syslog) message (message ID 305006), that could cause a reload of the Cisco ASA if this syslog message needs to be generated. Syslog message ID 305006 is generated when the Cisco ASA is unable to create a network address translation for a new connection. Additional information regarding this syslog message can be found in the Cisco ASA System Log Messages guide at: http://www.cisco.com/en/US/products/ps6120/products_system_message_guides_list.html Logging is not enabled by default on Cisco ASA, however, when logging is enabled, Cisco ASA will automatically enable syslog message 305006. Cisco ASA Software may be affected by this vulnerability if the following conditions are satisfied: * System logging is enabled and syslogs are configured to be sent to any syslog destination (including Buffer or ASDM for example) * Cisco ASA Software is configured in any way to generate syslog message 305006 Syslog message 305006 has a default severity level of 3 (errors). Cisco ASA Software configured for logging at Level 3 or higher (that is Levels 3 through 7) may be vulnerable. To verify if logging is enabled, issue the show logging command. The following example shows a Cisco ASA with logging enabled and buffer logging enabled at Level 6 (informational): ciscoasa# show logging Syslog logging: enabled Facility: 20 Timestamp logging: disabled Standby logging: disabled Debug-trace logging: disabled Console logging: disabled Monitor logging: disabled Buffer logging: level informational, 2 messages logged Trap logging: disabled Permit-hostdown logging: disabled History logging: disabled Device ID: disabled Mail logging: disabled ASDM logging: disabled Using a custom message list (created via the logging list command) that includes syslog message 305006, either by severity or by explicitly including the message ID, is also a vulnerable configuration. The default severity level of syslog messages can be changed. If the default severity level of syslog message 305006 is changed and the device is configured to log to any destination at the new severity level, the device is vulnerable. Note: This vulnerability was introduced after the implementation of the new Cisco ASA Identity Firewall (IDFW) feature. This feature is not enabled by default. To verify if PIM is enabled on an interface use the show pim interface command and verify that the state on appears under the PIM column. The following example shows PIM enabled on the interface outside but disabled on the interface inside: ciscoasa# show pim interface Address Interface PIM Nbr Hello DR DR Count Intvl Prior 192.168.1.1 outside on 0 30 1 this system 192.168.2.1 inside off 0 30 1 this system Note: Cisco ASA is vulnerable if at least one interface state is marked with on under the PIM column of the show pim interface command output. Determine the Running Software Version +------------------------------------- To determine whether a vulnerable version of Cisco ASA Software is running on an appliance, administrators can issue the show version command. Cisco PIX has reached end of maintenance support. Cisco PIX customers are encouraged to migrate to Cisco ASA. Details ======= The following section gives additional detail about each vulnerability. Cisco ASA UDP Inspection Engine Denial of Service Vulnerability +-------------------------------------------------------------- Inspection engines are required for services that embed IP addressing information in the user data packet or that open secondary channels on dynamically assigned ports. Cisco ASA Software supports a number of inspection engines for UDP and TCP-based protocols. The Cisco ASA UDP inspection engine that is used to inspect UDP-based protocols contains a vulnerability that could allow a remote unauthenticated attacker to trigger a reload of the Cisco ASA. The vulnerability is due to improper flow handling by the inspection engine. An attacker could exploit this vulnerability by sending a specially crafted sequence through the affected system. All UDP protocols that are inspected by the inspection engine may be vulnerable to this vulnerability. The following protocols are known to use UDP inspection engine: * Domain Name System (DNS) * Session Initiation Protocol (SIP) * Simple Network Management Protocol (SNMP) * GPRS Tunneling Protocol (GTP) * H.323, H.225 RAS * Media Gateway Control Protocol (MGCP) * SunRPC * Trivial File Transfer Protocol (TFTP) * X Display Manager Control Protocol (XDMCP) * IBM NetBios * Instant Messaging (depending on the particular IM client/solution being used) Inspection engines may be enabled by default on Cisco ASA Software. Please consult your user guide for more information. The default inspected ports are listed at the following link: http://www.cisco.com/en/US/docs/security/asa/asa84/configuration/guide/inspect_overview.html#wp1536127 Note: Only transit traffic can be used to exploit this vulnerability. This vulnerability affects both routed and transparent firewall mode in both single and multi-context mode. This vulnerability can be triggered by IPv4 and IPv6 traffic. Only UDP traffic can trigger this vulnerability. Cisco ASA Threat Detection Denial of Service Vulnerability +--------------------------------------------------------- The Cisco ASA Threat Detection feature consists of different levels of statistics gathered for various threats, as well as scanning threat detection, which determines when a host is performing a scan. Optionally, you can shun any hosts that are determined to be a scanning threat. The Cisco ASA Threat Detection feature, when configured with the Cisco ASA Scanning Threat Mode feature and with the shun option enabled, contains a vulnerability that could allow a remote, unauthenticated attacker to trigger a reload of the Cisco ASA. The vulnerability is due to improper handling of the internal flaw that is triggered by the shun event. An attacker may exploit this vulnerability by sending IP packets through the affected system in a way that triggers the shun option of Threat Detection scanning feature. Note: Only transit traffic can be used to exploit this vulnerability. This vulnerability affects both routed and transparent firewall mode only in single context mode. This vulnerability can be triggered by IPv4 and IPv6 traffic. Syslog messages are assigned different severities (including debugging, informational, error and critical, for example) and can be sent to different logging destinations. A denial of service vulnerability is in the implementation of one specific syslog message (message ID 305006), that can cause a reload of the Cisco ASA if this syslog message needs to be generated. An attacker could exploit this vulnerability by sending a sequence of packets that could trigger the generation of the syslog message. Syslog message ID 305006 is generated when the Cisco ASA is unable to create a network address translation for a new connection. Additional information about this syslog message can be found in the Cisco ASA System Log Messages guide: http://www.cisco.com/en/US/products/ps6120/products_system_message_guides_list.html Note: Only transit traffic can be used to exploit this vulnerability. This vulnerability affects both routed and transparent firewall mode in both single and multi-context mode. This vulnerability can be triggered by IPv4 and IPv6 traffic. Protocol-Independent Multicast Denial of Service Vulnerability +------------------------------------------------------------- Multicast routing is a bandwidth-conserving technology that reduces traffic by simultaneously delivering a single stream of information to multiple recipients. Protocol-independent multicast (PIM) is a multicast routing protocol that is IP routing protocol-independent. PIM can leverage whatever unicast routing protocols are used to populate the unicast routing table, including EIGRP, OSPF, BGP, or static routes. PIM uses this unicast routing information to perform the multicast forwarding function, and is IP protocol-independent. Although PIM is called a multicast routing protocol, it actually uses the unicast routing table to perform the reverse path forwarding (RPF) check function instead of building a completely independent multicast routing table. PIM does not send or receive multicast routing updates between routers as do other routing protocols. A vulnerability exists in the way PIM is implemented that may cause affected devices to reload during the processing of a PIM message when multicast routing is enabled. The vulnerability is due to improper handling of a PIM message. An attacker could exploit this vulnerability by sending a crafted PIM message to the affected system. Note: This vulnerability affects Cisco ASA configured only in routed firewall mode and only in single context mode. This vulnerability can be triggered only by IPv4 PIM message as PIM over IPv6 is currently not supported. Vulnerability Scoring Details ============================= Cisco has scored the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS).

Please note that some of these versions are interim versions and they can be found by expanding the Interim tab on the download page. Workarounds =========== The following section will detail the workaround if available for each vulnerability detailed in this security advisory. Cisco ASA UDP Inspection Engine Denial of Service Vulnerability +-------------------------------------------------------------- There are no workarounds that mitigate this vulnerability. Cisco ASA Threat Detection Denial of Service Vulnerability +--------------------------------------------------------- If the shun option needs to be enabled, there are no workarounds that mitigate this vulnerability. However, if this option is not required, you can workaround this vulnerability by disabling this option. This can be done by issuing the no threat-detection scanning-threat shun command. The threat-detection scanning-threat command can be used afterwards to configure the feature without the shun option. To verify that the shun option has been correctly removed, issue the show running-config threat-detection scanning-threat command and confirm that the returned output does not show the shun option. The following example shows a Cisco ASA configured with the threat-detection scanning-threat feature without the shun option enabled: ciscoasa# show running-config threat-detection scanning-threat threat-detection scanning-threat Cisco ASA Syslog Message 305006 Denial of Service Vulnerability +-------------------------------------------------------------- A possible workaround is to prevent the Cisco ASA from generating the particular syslog message. This can be done by issuing the no logging message 305006 command. To verify that the message is not being generated issue show running-configuration logging command. The following example shows the output of the command when the logging of message 305006 is disabled: ciscoasa# show run logging [...] no logging message 305006 [...] Protocol-Independent Multicast Denial of Service Vulnerability +------------------------------------------------------------- If PIM is required to be enabled, then there are no workarounds that mitigate this vulnerability. However, if multicast routing is required but PIM is not used, PIM can be disabled on the Cisco ASA interfaces by issuing the no pim interface-level command. The following example shows the interface Ethernet0/0 on a Cisco ASA device with PIM disabled: interface Ethernet0/0 nameif outside security-level 0 ip address 192.168.1.1 255.255.255.0 no pim To verify that PIM is disabled on all interfaces, issue the show pim interface command and make sure that for all interface the PIM state is set to off. The following example shows a Cisco ASA with PIM disabled on all interfaces. ciscoasa# show pim interface Address Interface PIM Nbr Hello DR DR Count Intvl Prior 192.168.1.1 outside off 0 30 1 this system 192.168.2.1 inside off 0 30 1 this system Obtaining Fixed Software ======================== Cisco has released free software updates that address the vulnerabilities described in this advisory.

Affected versions of Cisco ASA Software will vary depending on the specific vulnerability. Consult the "Software Versions and Fixes" section of this security advisory for more information about the affected version. Cisco PIX Security Appliances may be affected by some of the vulnerabilities described in this security advisory. Cisco PIX has reached end of maintenance support. Vulnerable Products +------------------ For specific version information, refer to the "Software Versions and Fixes" section of this advisory. The following protocols are known to use the Cisco ASA UDP inspection engine: * Domain Name System (DNS) * Session Initiation Protocol (SIP) * Simple Network Management Protocol (SNMP) * GPRS Tunneling Protocol (GTP) * H.323, H.225 RAS * Media Gateway Control Protocol (MGCP) * SunRPC * Trivial File Transfer Protocol (TFTP) * X Display Manager Control Protocol (XDMCP) * IBM NetBios * Instant Messaging (depending on the particular IM client/solution being used) Note: UDP inspection engines may be enabled by default on Cisco ASA Software. Please consult your user guide for more information. The default inspected ports are listed at the following link: http://www.cisco.com/en/US/docs/security/asa/asa84/configuration/guide/inspect_overview.html Note: The Cisco ASA UDP inspection can be applied to non-default UDP ports via class-map and policy-map commands. To determine whether any of the above inspections are enabled, issue the show service-policy | include <inspection engine name> command and confirm that the command returns output. The following example shows a Cisco ASA configured to inspect IBM NetBIOS traffic: ciscoasa# show service-policy | include netbios Inspect: netbios, packet 0, drop 0, reset-drop 0 Cisco ASA Threat Detection Denial of Service Vulnerability +--------------------------------------------------------- The Cisco ASA Threat Detection feature, when configured with the Scanning Threat Mode feature and with shun option enabled, contains a vulnerability that could allow a remote unauthenticated attacker to trigger a reload of the Cisco ASA. This feature is not enabled by default. To determine whether the Cisco ASA Threat Detection with Scanning Threat feature and shun option is enabled, issue the show running-config threat-detection scanning-threat command and confirm that the returned output includes the shun option. Cisco ASA Syslog Message 305006 Denial of Service Vulnerability +-------------------------------------------------------------- A denial of service (DoS) vulnerability exists in the implementation of one specific system log (syslog) message (message ID 305006), that could cause a reload of the Cisco ASA if this syslog message needs to be generated. Syslog message ID 305006 is generated when the Cisco ASA is unable to create a network address translation for a new connection. Additional information regarding this syslog message can be found in the Cisco ASA System Log Messages guide at: http://www.cisco.com/en/US/products/ps6120/products_system_message_guides_list.html Logging is not enabled by default on Cisco ASA, however, when logging is enabled, Cisco ASA will automatically enable syslog message 305006. Cisco ASA Software may be affected by this vulnerability if the following conditions are satisfied: * System logging is enabled and syslogs are configured to be sent to any syslog destination (including Buffer or ASDM for example) * Cisco ASA Software is configured in any way to generate syslog message 305006 Syslog message 305006 has a default severity level of 3 (errors). Cisco ASA Software configured for logging at Level 3 or higher (that is Levels 3 through 7) may be vulnerable. To verify if logging is enabled, issue the show logging command. The following example shows a Cisco ASA with logging enabled and buffer logging enabled at Level 6 (informational): ciscoasa# show logging Syslog logging: enabled Facility: 20 Timestamp logging: disabled Standby logging: disabled Debug-trace logging: disabled Console logging: disabled Monitor logging: disabled Buffer logging: level informational, 2 messages logged Trap logging: disabled Permit-hostdown logging: disabled History logging: disabled Device ID: disabled Mail logging: disabled ASDM logging: disabled Using a custom message list (created via the logging list command) that includes syslog message 305006, either by severity or by explicitly including the message ID, is also a vulnerable configuration. The default severity level of syslog messages can be changed. If the default severity level of syslog message 305006 is changed and the device is configured to log to any destination at the new severity level, the device is vulnerable. Note: This vulnerability was introduced after the implementation of the new Cisco ASA Identity Firewall (IDFW) feature. Protocol-Independent Multicast Denial of Service Vulnerability +------------------------------------------------------------- Cisco ASA Sofware is affected by a vulnerability that may cause affected devices to reload during the processing of Protocol-Indipendent Multicast (PIM) message when multicast routing is enabled. This feature is not enabled by default. To verify if PIM is enabled on an interface use the show pim interface command and verify that the state on appears under the PIM column. The following example shows PIM enabled on the interface outside but disabled on the interface inside: ciscoasa# show pim interface Address Interface PIM Nbr Hello DR DR Count Intvl Prior 192.168.1.1 outside on 0 30 1 this system 192.168.2.1 inside off 0 30 1 this system Note: Cisco ASA is vulnerable if at least one interface state is marked with on under the PIM column of the show pim interface command output. Determine the Running Software Version +------------------------------------- To determine whether a vulnerable version of Cisco ASA Software is running on an appliance, administrators can issue the show version command. Cisco PIX has reached end of maintenance support. Cisco PIX customers are encouraged to migrate to Cisco ASA. All versions of the Cisco PIX Security Appliances Software are affected by the Protocol-Independent Multicast Denial of Service Vulnerability. Details ======= The following section gives additional detail about each vulnerability. The vulnerability is due to improper flow handling by the inspection engine. An attacker could exploit this vulnerability by sending a specially crafted sequence through the affected system. The following protocols are known to use UDP inspection engine: * Domain Name System (DNS) * Session Initiation Protocol (SIP) * Simple Network Management Protocol (SNMP) * GPRS Tunneling Protocol (GTP) * H.323, H.225 RAS * Media Gateway Control Protocol (MGCP) * SunRPC * Trivial File Transfer Protocol (TFTP) * X Display Manager Control Protocol (XDMCP) * IBM NetBios * Instant Messaging (depending on the particular IM client/solution being used) Inspection engines may be enabled by default on Cisco ASA Software. Please consult your user guide for more information. The default inspected ports are listed at the following link: http://www.cisco.com/en/US/docs/security/asa/asa84/configuration/guide/inspect_overview.html#wp1536127 Note: Only transit traffic can be used to exploit this vulnerability. This vulnerability affects both routed and transparent firewall mode in both single and multi-context mode. This vulnerability can be triggered by IPv4 and IPv6 traffic. Only UDP traffic can trigger this vulnerability. Cisco ASA Threat Detection Denial of Service Vulnerability +--------------------------------------------------------- The Cisco ASA Threat Detection feature consists of different levels of statistics gathered for various threats, as well as scanning threat detection, which determines when a host is performing a scan. Optionally, you can shun any hosts that are determined to be a scanning threat. The Cisco ASA Threat Detection feature, when configured with the Cisco ASA Scanning Threat Mode feature and with the shun option enabled, contains a vulnerability that could allow a remote, unauthenticated attacker to trigger a reload of the Cisco ASA. The vulnerability is due to improper handling of the internal flaw that is triggered by the shun event. An attacker may exploit this vulnerability by sending IP packets through the affected system in a way that triggers the shun option of Threat Detection scanning feature. Note: Only transit traffic can be used to exploit this vulnerability. This vulnerability affects both routed and transparent firewall mode only in single context mode. This vulnerability can be triggered by IPv4 and IPv6 traffic. Syslog messages are assigned different severities (including debugging, informational, error and critical, for example) and can be sent to different logging destinations. A denial of service vulnerability is in the implementation of one specific syslog message (message ID 305006), that can cause a reload of the Cisco ASA if this syslog message needs to be generated. An attacker could exploit this vulnerability by sending a sequence of packets that could trigger the generation of the syslog message. Syslog message ID 305006 is generated when the Cisco ASA is unable to create a network address translation for a new connection. Additional information about this syslog message can be found in the Cisco ASA System Log Messages guide: http://www.cisco.com/en/US/products/ps6120/products_system_message_guides_list.html Note: Only transit traffic can be used to exploit this vulnerability. This vulnerability affects both routed and transparent firewall mode in both single and multi-context mode. This vulnerability can be triggered by IPv4 and IPv6 traffic. Protocol-Independent Multicast Denial of Service Vulnerability +------------------------------------------------------------- Multicast routing is a bandwidth-conserving technology that reduces traffic by simultaneously delivering a single stream of information to multiple recipients. Protocol-independent multicast (PIM) is a multicast routing protocol that is IP routing protocol-independent. PIM can leverage whatever unicast routing protocols are used to populate the unicast routing table, including EIGRP, OSPF, BGP, or static routes. PIM uses this unicast routing information to perform the multicast forwarding function, and is IP protocol-independent. Although PIM is called a multicast routing protocol, it actually uses the unicast routing table to perform the reverse path forwarding (RPF) check function instead of building a completely independent multicast routing table. PIM does not send or receive multicast routing updates between routers as do other routing protocols. A vulnerability exists in the way PIM is implemented that may cause affected devices to reload during the processing of a PIM message when multicast routing is enabled. The vulnerability is due to improper handling of a PIM message. An attacker could exploit this vulnerability by sending a crafted PIM message to the affected system. Note: This vulnerability affects Cisco ASA configured only in routed firewall mode and only in single context mode. This vulnerability can be triggered only by IPv4 PIM message as PIM over IPv6 is currently not supported.

Please note that some of these versions are interim versions and they can be found by expanding the Interim tab on the download page. Workarounds =========== The following section will detail the workaround if available for each vulnerability detailed in this security advisory. Cisco ASA Threat Detection Denial of Service Vulnerability +--------------------------------------------------------- If the shun option needs to be enabled, there are no workarounds that mitigate this vulnerability. However, if this option is not required, you can workaround this vulnerability by disabling this option. This can be done by issuing the no threat-detection scanning-threat shun command. The threat-detection scanning-threat command can be used afterwards to configure the feature without the shun option. To verify that the shun option has been correctly removed, issue the show running-config threat-detection scanning-threat command and confirm that the returned output does not show the shun option. The following example shows a Cisco ASA configured with the threat-detection scanning-threat feature without the shun option enabled: ciscoasa# show running-config threat-detection scanning-threat threat-detection scanning-threat Cisco ASA Syslog Message 305006 Denial of Service Vulnerability +-------------------------------------------------------------- A possible workaround is to prevent the Cisco ASA from generating the particular syslog message. This can be done by issuing the no logging message 305006 command. To verify that the message is not being generated issue show running-configuration logging command. The following example shows the output of the command when the logging of message 305006 is disabled: ciscoasa# show run logging [...] no logging message 305006 [...] Protocol-Independent Multicast Denial of Service Vulnerability +------------------------------------------------------------- If PIM is required to be enabled, then there are no workarounds that mitigate this vulnerability. However, if multicast routing is required but PIM is not used, PIM can be disabled on the Cisco ASA interfaces by issuing the no pim interface-level command. The following example shows the interface Ethernet0/0 on a Cisco ASA device with PIM disabled: interface Ethernet0/0 nameif outside security-level 0 ip address 192.168.1.1 255.255.255.0 no pim To verify that PIM is disabled on all interfaces, issue the show pim interface command and make sure that for all interface the PIM state is set to off. ciscoasa# show pim interface Address Interface PIM Nbr Hello DR DR Count Intvl Prior 192.168.1.1 outside off 0 30 1 this system 192.168.2.1 inside off 0 30 1 this system Obtaining Fixed Software ======================== Cisco has released free software updates that address the vulnerabilities described in this advisory.

The following protocols are known to use the Cisco ASA UDP inspection engine: * Domain Name System (DNS) * Session Initiation Protocol (SIP) * Simple Network Management Protocol (SNMP) * GPRS Tunneling Protocol (GTP) * H.323, H.225 RAS * Media Gateway Control Protocol (MGCP) * SunRPC * Trivial File Transfer Protocol (TFTP) * X Display Manager Control Protocol (XDMCP) * IBM NetBios * Instant Messaging (depending on the particular IM client/solution being used) Note: UDP inspection engines may be enabled by default on Cisco ASA Software. Please consult your user guide for more information. The default inspected ports are listed at the following link: http://www.cisco.com/en/US/docs/security/asa/asa84/configuration/guide/inspect_overview.html Note: The Cisco ASA UDP inspection can be applied to non-default UDP ports via class-map and policy-map commands. Any instance of use of the Cisco ASA UDP inspection engines may be vulnerable to this vulnerability, thus, configurations that include non-default UDP ports but use the Cisco ASA UDP inspection engine are considered vulnerable. To determine whether any of the above inspections are enabled, issue the show service-policy | include <inspection engine name> command and confirm that the command returns output. This feature is not enabled by default. To determine whether the Cisco ASA Threat Detection with Scanning Threat feature and shun option is enabled, issue the show running-config threat-detection scanning-threat command and confirm that the returned output includes the shun option. Cisco ASA Syslog Message 305006 Denial of Service Vulnerability +-------------------------------------------------------------- A denial of service (DoS) vulnerability exists in the implementation of one specific system log (syslog) message (message ID 305006), that could cause a reload of the Cisco ASA if this syslog message needs to be generated. Syslog message ID 305006 is generated when the Cisco ASA is unable to create a network address translation for a new connection. Additional information regarding this syslog message can be found in the Cisco ASA System Log Messages guide at: http://www.cisco.com/en/US/products/ps6120/products_system_message_guides_list.html Logging is not enabled by default on Cisco ASA, however, when logging is enabled, Cisco ASA will automatically enable syslog message 305006. Cisco ASA Software may be affected by this vulnerability if the following conditions are satisfied: * System logging is enabled and syslogs are configured to be sent to any syslog destination (including Buffer or ASDM for example) * Cisco ASA Software is configured in any way to generate syslog message 305006 Syslog message 305006 has a default severity level of 3 (errors). Cisco ASA Software configured for logging at Level 3 or higher (that is Levels 3 through 7) may be vulnerable. To verify if logging is enabled, issue the show logging command. The following example shows a Cisco ASA with logging enabled and buffer logging enabled at Level 6 (informational): ciscoasa# show logging Syslog logging: enabled Facility: 20 Timestamp logging: disabled Standby logging: disabled Debug-trace logging: disabled Console logging: disabled Monitor logging: disabled Buffer logging: level informational, 2 messages logged Trap logging: disabled Permit-hostdown logging: disabled History logging: disabled Device ID: disabled Mail logging: disabled ASDM logging: disabled Using a custom message list (created via the logging list command) that includes syslog message 305006, either by severity or by explicitly including the message ID, is also a vulnerable configuration. The default severity level of syslog messages can be changed. If the default severity level of syslog message 305006 is changed and the device is configured to log to any destination at the new severity level, the device is vulnerable. Note: This vulnerability was introduced after the implementation of the new Cisco ASA Identity Firewall (IDFW) feature. Protocol-Independent Multicast Denial of Service Vulnerability +------------------------------------------------------------- Cisco ASA Sofware is affected by a vulnerability that may cause affected devices to reload during the processing of Protocol-Indipendent Multicast (PIM) message when multicast routing is enabled. This feature is not enabled by default. To verify if PIM is enabled on an interface use the show pim interface command and verify that the state on appears under the PIM column. The following example shows PIM enabled on the interface outside but disabled on the interface inside: ciscoasa# show pim interface Address Interface PIM Nbr Hello DR DR Count Intvl Prior 192.168.1.1 outside on 0 30 1 this system 192.168.2.1 inside off 0 30 1 this system Note: Cisco ASA is vulnerable if at least one interface state is marked with on under the PIM column of the show pim interface command output. Determine the Running Software Version +------------------------------------- To determine whether a vulnerable version of Cisco ASA Software is running on an appliance, administrators can issue the show version command. Cisco PIX has reached end of maintenance support. Cisco PIX customers are encouraged to migrate to Cisco ASA. Details ======= The following section gives additional detail about each vulnerability. Cisco ASA UDP Inspection Engine Denial of Service Vulnerability +-------------------------------------------------------------- Inspection engines are required for services that embed IP addressing information in the user data packet or that open secondary channels on dynamically assigned ports. Cisco ASA Software supports a number of inspection engines for UDP and TCP-based protocols. The vulnerability is due to improper flow handling by the inspection engine. An attacker could exploit this vulnerability by sending a specially crafted sequence through the affected system. All UDP protocols that are inspected by the inspection engine may be vulnerable to this vulnerability. The following protocols are known to use UDP inspection engine: * Domain Name System (DNS) * Session Initiation Protocol (SIP) * Simple Network Management Protocol (SNMP) * GPRS Tunneling Protocol (GTP) * H.323, H.225 RAS * Media Gateway Control Protocol (MGCP) * SunRPC * Trivial File Transfer Protocol (TFTP) * X Display Manager Control Protocol (XDMCP) * IBM NetBios * Instant Messaging (depending on the particular IM client/solution being used) Inspection engines may be enabled by default on Cisco ASA Software. Please consult your user guide for more information. The default inspected ports are listed at the following link: http://www.cisco.com/en/US/docs/security/asa/asa84/configuration/guide/inspect_overview.html#wp1536127 Note: Only transit traffic can be used to exploit this vulnerability. This vulnerability affects both routed and transparent firewall mode in both single and multi-context mode. This vulnerability can be triggered by IPv4 and IPv6 traffic. Only UDP traffic can trigger this vulnerability. Optionally, you can shun any hosts that are determined to be a scanning threat. The vulnerability is due to improper handling of the internal flaw that is triggered by the shun event. An attacker may exploit this vulnerability by sending IP packets through the affected system in a way that triggers the shun option of Threat Detection scanning feature. Note: Only transit traffic can be used to exploit this vulnerability. This vulnerability affects both routed and transparent firewall mode only in single context mode. This vulnerability can be triggered by IPv4 and IPv6 traffic. Syslog messages are assigned different severities (including debugging, informational, error and critical, for example) and can be sent to different logging destinations. A denial of service vulnerability is in the implementation of one specific syslog message (message ID 305006), that can cause a reload of the Cisco ASA if this syslog message needs to be generated. An attacker could exploit this vulnerability by sending a sequence of packets that could trigger the generation of the syslog message. Syslog message ID 305006 is generated when the Cisco ASA is unable to create a network address translation for a new connection. Additional information about this syslog message can be found in the Cisco ASA System Log Messages guide: http://www.cisco.com/en/US/products/ps6120/products_system_message_guides_list.html Note: Only transit traffic can be used to exploit this vulnerability. This vulnerability affects both routed and transparent firewall mode in both single and multi-context mode. This vulnerability can be triggered by IPv4 and IPv6 traffic. Protocol-Independent Multicast Denial of Service Vulnerability +------------------------------------------------------------- Multicast routing is a bandwidth-conserving technology that reduces traffic by simultaneously delivering a single stream of information to multiple recipients. Protocol-independent multicast (PIM) is a multicast routing protocol that is IP routing protocol-independent. PIM can leverage whatever unicast routing protocols are used to populate the unicast routing table, including EIGRP, OSPF, BGP, or static routes. PIM uses this unicast routing information to perform the multicast forwarding function, and is IP protocol-independent. Although PIM is called a multicast routing protocol, it actually uses the unicast routing table to perform the reverse path forwarding (RPF) check function instead of building a completely independent multicast routing table. PIM does not send or receive multicast routing updates between routers as do other routing protocols. A vulnerability exists in the way PIM is implemented that may cause affected devices to reload during the processing of a PIM message when multicast routing is enabled. The vulnerability is due to improper handling of a PIM message. An attacker could exploit this vulnerability by sending a crafted PIM message to the affected system. Note: This vulnerability affects Cisco ASA configured only in routed firewall mode and only in single context mode. This vulnerability can be triggered only by IPv4 PIM message as PIM over IPv6 is currently not supported.

Please note that some of these versions are interim versions and they can be found by expanding the Interim tab on the download page. Workarounds =========== The following section will detail the workaround if available for each vulnerability detailed in this security advisory. However, if this option is not required, you can workaround this vulnerability by disabling this option. This can be done by issuing the no threat-detection scanning-threat shun command. The threat-detection scanning-threat command can be used afterwards to configure the feature without the shun option. To verify that the shun option has been correctly removed, issue the show running-config threat-detection scanning-threat command and confirm that the returned output does not show the shun option. The following example shows a Cisco ASA configured with the threat-detection scanning-threat feature without the shun option enabled: ciscoasa# show running-config threat-detection scanning-threat threat-detection scanning-threat Cisco ASA Syslog Message 305006 Denial of Service Vulnerability +-------------------------------------------------------------- A possible workaround is to prevent the Cisco ASA from generating the particular syslog message. This can be done by issuing the no logging message 305006 command. To verify that the message is not being generated issue show running-configuration logging command. The following example shows the output of the command when the logging of message 305006 is disabled: ciscoasa# show run logging [...] no logging message 305006 [...] Protocol-Independent Multicast Denial of Service Vulnerability +------------------------------------------------------------- If PIM is required to be enabled, then there are no workarounds that mitigate this vulnerability. However, if multicast routing is required but PIM is not used, PIM can be disabled on the Cisco ASA interfaces by issuing the no pim interface-level command. The following example shows the interface Ethernet0/0 on a Cisco ASA device with PIM disabled: interface Ethernet0/0 nameif outside security-level 0 ip address 192.168.1.1 255.255.255.0 no pim To verify that PIM is disabled on all interfaces, issue the show pim interface command and make sure that for all interface the PIM state is set to off. ciscoasa# show pim interface Address Interface PIM Nbr Hello DR DR Count Intvl Prior 192.168.1.1 outside off 0 30 1 this system 192.168.2.1 inside off 0 30 1 this system Obtaining Fixed Software ======================== Cisco has released free software updates that address the vulnerabilities described in this advisory.
