These vulnerabilities are as follows: * Memory Leak Associated with Crafted IP Packets * Memory Leak in HTTP Inspection * Memory Leak in H.323 Inspection * Memory Leak in SIP Inspection Workarounds that mitigate these vulnerabilities are not available. Cisco has released free software updates that address these vulnerabilities. This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120328-zbfw Note: The March 28, 2012, Cisco IOS Software Security Advisory bundled publication includes nine Cisco Security Advisories. Each advisory lists the Cisco IOS Software releases that correct the vulnerability or vulnerabilities detailed in the advisory as well as the Cisco IOS Software releases that correct all vulnerabilities in the March 2012 bundled publication. The vulnerabilities are independent of each other. Details to confirm affected configurations are provided below. To determine whether a device is configured with Zone-Based Firewall, log in to the device and issue the show zone security command-line interface (CLI) command. If the output shows a member interface under a zone name, the device is vulnerable. The following example shows a device with Zone-Based Firewall rules configured on both GigabitEthernet0/0 and GigabitEthernet0/1: Router#show zone security zone self Description: System defined zone zone inside Description: *** Inside Network *** Member Interfaces: GigabitEthernet0/0 zone outside Description: *** Outside Network *** Member Interfaces: GigabitEthernet0/1 Router# The following sections provide more details on the specific features containing the vulnerabilities. If the Zone-Based Firewall is configured, the device is vulnerable. To determine whether a device is configured for HTTP inspection, enter the command show policy-map type inspect zone-pair | include Match: protocol http. To determine if a device is configured for H.323 inspection enter the command show policy-map type inspect zone-pair | include Match: protocol h323. If the output contains "Match: protocol h323" the device is vulnerable. The following example shows a vulnerable device configured with Cisco IOS Zone-Based Policy Firewall H.323 inspection: Router# show policy-map type inspect zone-pair | include Match: protocol h323 Match: protocol h323 Memory Leak in SIP Inspection +---------------------------- The device is vulnerable if the configuration has either a Layer 4 or Layer 7 Session Initiation Protocol (SIP) application-specific policy configured, and the policy is applied to any firewall zone. To determine whether a device is configured for SIP inspection enter the command show policy-map type inspect zone-pair | include Match: protocol sip. If the output contains "Match: protocol sip" the device is vulnerable. The following example shows a vulnerable device configured with Cisco IOS Zone-Based Policy Firewall SIP inspection: Router# show policy-map type inspect zone-pair | include Match: protocol sip Match: protocol sip To determine the Cisco IOS Software release that is running on a Cisco product, administrators can log in to the device and issue the show version command to display the system banner. Other Cisco devices do not have the show version command or may provide different output. The following example identifies a Cisco product that is running Cisco IOS Software Release 15.0(1)M1 with an installed image name of C3900-UNIVERSALK9-M: Router> show version Cisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.0(1)M1, RELEASE SOFTWARE (fc1) Technical Support: http://www.cisco.com/techsupport Copyright (c) 1986-2009 by Cisco Systems, Inc. Compiled Wed 02-Dec-09 17:17 by prod_rel_team !--- output truncated Additional information about Cisco IOS Software release naming conventions is available in "White Paper: Cisco IOS and NX-OS Software Reference Guide" at http://www.cisco.com/web/about/security/ intelligence/ios-ref.html. Products Confirmed Not Vulnerable +-------------------------------- The following products are confirmed not vulnerable: * Cisco PIX 500 Series Firewall * Cisco ASA 5500 Series Adaptive Security Appliance * Firewall Services Module (FWSM) for Catalyst 6500 Series Switches and 7600 Series Routers * Virtual Firewall (VFW) application on the multiservice blade (MSB) on the Cisco XR 12000 Series Router * Cisco ACE Application Control Engine Module * Cisco IOS devices configured with legacy Cisco IOS Firewall support * Cisco IOS XR Software * Cisco IOS XE Software * Cisco Catalyst 6500 Series ASA Services Module * Context-Based Access Control (CBAC) No other Cisco products are currently known to be affected by these vulnerabilities. Details ======= Firewalls are networking devices that control access to the network assets of an organization. Firewalls are often positioned at the entrance points of networks. The vulnerabilities described in this advisory affect the Zone-Based Firewall feature. The Zone-Based Policy Firewall (also known as Zone-Policy Firewall or ZFW) updates the firewall configuration from the older interface-based model to a more flexible, more easily understood zone-based model. Interfaces are assigned to zones, and inspection policy is applied to traffic moving between the zones. Inter-zone policies offer considerable flexibility and granularity, so different inspection policies can be applied to multiple host groups connected to the same router interface. These vulnerabilities are triggered when the device that is running Cisco IOS Software processes crafted IP packets. Only traffic destined to an IP address configured on the device can trigger the vulnerability; transit traffic is not an exploit vector. This vulnerability is documented in Cisco bug ID CSCto89536 and has been assigned the Common Vulnerabilities and Exposures (CVE) identifier CVE-2012-1310. Memory Leak in HTTP Inspection +--------------------------------------------- The HTTP Inspection Engine feature allows users to configure their Cisco IOS Firewall to detect and filter HTTP connections-such as tunneling over port 80, unauthorized request methods, and non-HTTP compliant file transfers-that are not authorized within the scope of the security policy configuration. This vulnerability is triggered when the device that is running Cisco IOS Software processes certain HTTP messages. Transit HTTP traffic is an exploit vector. This vulnerability is documented in Cisco bug ID CSCtq36153 and has been assigned CVE ID CVE-2012-0387. More information on HTTP inspection is available at: http://www.cisco.com/en/US/docs/ios/12_3t/12_3t14/feature/guide/gt_fwapc.html Memory Leak in H.323 Inspection +--------------------------------------------- H.323 is the ITU standard for real-time multimedia communications and conferencing over packet-based (IP) networks. This vulnerability is triggered when the device that is running Cisco IOS Software processes malformed H.323 messages. Transit H.323 traffic is an exploit vector. This vulnerability is documented in Cisco bug ID CSCtq45553 and has been assigned the CVE ID CVE-2012-0388. More information on H.323 inspection is available at: http://www.cisco.com/en/US/docs/ios-xml/ios/sec_data_zbf/configuration/15-2mt/fw-h323-v3v4-sup.html Memory Leak in SIP Inspection +--------------------------------------------- SIP is a popular signaling protocol that is used to manage voice and video calls across IP networks, such as the Internet. SIP is responsible for handling all aspects of call setup and termination. Voice and video are the most popular types of sessions that SIP handles, but the protocol has the flexibility to accommodate other applications that require call setup and termination. SIP call signaling can use UDP (port 5060), TCP (port 5060), or Transport Layer Security (TLS; TCP port 5061) as the underlying transport protocol. This vulnerability is triggered when the device that is running Cisco IOS Software processes crafted SIP messages. Transit SIP traffic is an exploit vector. This vulnerability is documented in Cisco bug ID CSCti46171 and has been assigned CVE ID CVE-2012-1315. More information on SIP inspection is available at: http://www.cisco.com/en/US/docs/ios/security/configuration/guide/sec_sip_alg_aic.html Memory Leak Detection +--------------------------------------------- Detected memory leaks can be viewed using the command show memory debug leaks chunks in privileged EXEC mode, as shown in the following example: Router# show memory debug leaks chunks Adding blocks for GD... I/O memory Address Size Alloc_pc PID Alloc-Proc Name Chunk Elements: AllocPC Address Size Parent Name Processor memory Address Size Alloc_pc PID Alloc-Proc Name 4733113C 188 419CB164 129 IP Input FW h225 tpkt The previous example shows a memory leak in the process FW h225 tpkt. The show memory debug leaks command was introduced in Cisco IOS Software versions 12.3(8)T1 and 12.2(25)S. Caution: All show memory debug commands must be used on customer networks only to diagnose the router for memory leaks when memory depletion is observed. These commands may cause high CPU utilization and may cause time-sensitive protocols to flap. These commands are recommended to be used in maintenance windows. Vulnerability Scoring Details ============================= Cisco has scored the vulnerabilities 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.

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 * Memory Leak associated with crafted IP packets 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 * Memory Leak in HTTP inspection 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 * Memory Leak in H.323 inspection 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 * Memory Leak in SIP Inspection 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 a reload of the affected device. Repeated exploit attempts may result in a sustained denial of service (DoS) attack. 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. If a particular train is vulnerable, the earliest releases that contain the fix are listed in the First Fixed Release column. The First Fixed Release for All Advisories in the March 2012 Bundled Publication column lists the earliest possible releases that correct all the published vulnerabilities in the Cisco IOS Software Security Advisory bundled publication.

| | | 15.2(2)T1 | Available on | | | | 30-MAR-12 | +------------------------------------------+ * Cisco Catalyst 3550 Series Switches support the Internet Key Exchange (IKE) feature and are vulnerable to Cisco bug ID CSCts38429 when the devices are running Layer 3 images; however, this product reached the End of Software Maintenance milestone. Cisco 3550 Series SMI Switches that are running Layer 2 images do not support IKE and are not vulnerable. No other Cisco devices that run 12.2SE-based software are vulnerable. Workarounds =========== There are no workarounds that mitigate the vulnerabilities described in this advisory. Obtaining Fixed Software ======================== Cisco has released free software updates that address the vulnerabilities described in this advisory. Prior to deploying software, customers are advised to consult their maintenance providers or check the software for feature set compatibility and known issues that are specific to their environments. Customers may only install and expect support for feature sets they have purchased. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license at: http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html or as set forth at http://www.cisco.com/public/sw-center/sw-usingswc.shtml Do not contact 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, upgrades should be obtained through the Software Center on Cisco.com at: http://www.cisco.com Customers Using Third-Party Support Organizations +------------------------------------------------ Customers with Cisco products that are provided or maintained through prior or existing agreements with third-party support organizations, such as Cisco Partners, authorized resellers, or service providers, should contact that organization for assistance with the appropriate course of action. The effectiveness of any workaround or fix depends on specific customer situations, such as product mix, network topology, traffic behavior, and organizational mission. Because of the variety of affected products and releases, customers should consult their service providers or support organizations to ensure that any applied workaround or fix is the most appropriate in the intended network before it is deployed. Customers Without Service Contracts +---------------------------------- Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco Technical Assistance Center (TAC): * +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 Customers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade. Customers without service contracts should request free upgrades through the TAC. Refer to Cisco Worldwide Contacts at: http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html for additional TAC contact information, including localized telephone numbers, instructions, and e-mail addresses for support in various languages.
