Summary
Cisco IOS Software contains four vulnerabilities related to Cisco IOS Zone-Based Firewall features. 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.
Individual publication links are in "Cisco Event Response: Semi-Annual Cisco IOS Software Security Advisory Bundled Publication" at the following link:
http://www.cisco.com/web/about/security/intelligence/Cisco_ERP_mar12.html
Affected Products
Vulnerable Products +------------------
Cisco IOS devices running vulnerable versions of Cisco IOS Software are affected by four vulnerabilities in the Cisco IOS Zone-Based Firewall. 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.
Memory Leak Associated with Crafted IP Packets +--------------------------------------------- There is no specific configuration necessary for a device to be vulnerable to the memory leak associated with crafted IP packets. 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.

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. Cisco IOS Software provides a set of security features that allow the configuration of a firewall policy to match an organization's requirements.
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. 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. 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. 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. 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.
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. Customers can also compute environmental scores that help determine the impact of the vulnerability in their own networks.

- 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.
For a mapping of Cisco IOS XE Software releases to Cisco IOS Software releases, refer to Cisco IOS XE 2 Release Notes, Cisco IOS XE 3S Release Notes, and Cisco IOS XE 3SG Release Notes.
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.

These vulnerabilities are as follows:\n\n * Memory Leak Associated with Crafted IP Packets \n * Memory Leak in HTTP Inspection \n * Memory Leak in H.323 Inspection \n * Memory Leak in SIP Inspection \n\nWorkarounds that mitigate these vulnerabilities are not available. \n\nCisco has released free software updates that address these\nvulnerabilities. \n\nThis advisory is available at the following link: \nhttp://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20120328-zbfw\n\n\nNote: The March 28, 2012, Cisco IOS Software Security Advisory\nbundled publication includes nine Cisco Security Advisories. \n\nIndividual publication links are in \"Cisco Event Response:\nSemi-Annual Cisco IOS Software Security Advisory Bundled Publication\"\nat the following link:\n\nhttp://www.cisco.com/web/about/security/intelligence/Cisco_ERP_mar12.html\n\nAffected Products\n=================\n\n\nVulnerable Products\n+------------------\n\nCisco IOS devices running vulnerable versions of Cisco IOS Software\nare affected by four vulnerabilities in the Cisco IOS Zone-Based\nFirewall. The vulnerabilities are independent of each other. Details\nto confirm affected configurations are provided below. \n\nTo determine whether a device is configured with Zone-Based Firewall,\nlog in to the device and issue the show zone security command-line\ninterface (CLI) command. If the output shows a member interface under\na zone name, the device is vulnerable. The following example shows a\ndevice with Zone-Based Firewall rules configured on both\nGigabitEthernet0/0 and GigabitEthernet0/1:\n\n Router#show zone security\n zone self\n Description: System defined zone\n \n zone inside\n Description: *** Inside Network ***\n Member Interfaces:\n GigabitEthernet0/0\n \n zone outside\n Description: *** Outside Network ***\n Member Interfaces:\n GigabitEthernet0/1\n \n Router#\n\nThe following sections provide more details on the specific features\ncontaining the vulnerabilities. \n\nMemory Leak Associated with Crafted IP Packets\n+---------------------------------------------\nThere is no specific configuration necessary for a device to be\nvulnerable to the memory leak associated with crafted IP packets. If\nthe Zone-Based Firewall is configured, the device is vulnerable. \n\nTo determine whether a device is configured for HTTP inspection,\nenter the command show policy-map type inspect zone-pair | include\nMatch: protocol http. To determine if a device is configured for\nH.323 inspection enter the command show policy-map type inspect\nzone-pair | include Match: protocol h323. If the output contains\n\"Match: protocol h323\" the device is vulnerable. The following\nexample shows a vulnerable device configured with Cisco IOS\nZone-Based Policy Firewall H.323 inspection:\n\nRouter# show policy-map type inspect zone-pair | include Match: protocol h323\n Match: protocol h323\n\nMemory Leak in SIP Inspection\n+----------------------------\nThe device is vulnerable if the configuration has either a Layer 4 or\nLayer 7 Session Initiation Protocol (SIP) application-specific policy\nconfigured, and the policy is applied to any firewall zone. To\ndetermine whether a device is configured for SIP inspection enter the\ncommand show policy-map type inspect zone-pair | include Match:\nprotocol sip. If the output contains \"Match: protocol sip\" the device\nis vulnerable. The following example shows a vulnerable device\nconfigured with Cisco IOS Zone-Based Policy Firewall SIP inspection:\n\nRouter# show policy-map type inspect zone-pair | include Match: protocol sip \n Match: protocol sip\n\nTo determine the Cisco IOS Software release that is running on a\nCisco product, administrators can log in to the device and issue the \nshow version command to display the system banner. Other\nCisco devices do not have the show version command or may provide\ndifferent output. \n\nThe following example identifies a Cisco product that is running\nCisco IOS Software Release 15.0(1)M1 with an installed image name of\nC3900-UNIVERSALK9-M:\n\nRouter\u003e show version \nCisco IOS Software, C3900 Software (C3900-UNIVERSALK9-M), Version 15.0(1)M1, RELEASE SOFTWARE (fc1)\nTechnical Support: http://www.cisco.com/techsupport\nCopyright (c) 1986-2009 by Cisco Systems, Inc. \nCompiled Wed 02-Dec-09 17:17 by prod_rel_team\n!--- output truncated \n\nAdditional information about Cisco IOS Software release naming\nconventions is available in \"White Paper: Cisco IOS and NX-OS\nSoftware Reference Guide\" at http://www.cisco.com/web/about/security/\nintelligence/ios-ref.html. \n\n\n\nProducts Confirmed Not Vulnerable\n+--------------------------------\n\nThe following products are confirmed not vulnerable:\n\n * Cisco PIX 500 Series Firewall\n * Cisco ASA 5500 Series Adaptive Security Appliance\n * Firewall Services Module (FWSM) for Catalyst 6500 Series Switches\n and 7600 Series Routers\n * Virtual Firewall (VFW) application on the multiservice blade\n (MSB) on the Cisco XR 12000 Series Router\n * Cisco ACE Application Control Engine Module\n * Cisco IOS devices configured with legacy Cisco IOS Firewall\n support \n * Cisco IOS XR Software\n * Cisco IOS XE Software\n * Cisco Catalyst 6500 Series ASA Services Module\n * Context-Based Access Control (CBAC) \n\nNo other Cisco products are currently known to be affected by these\nvulnerabilities. \n\nDetails\n=======\n\nFirewalls are networking devices that control access to the network\nassets of an organization. Firewalls are often positioned at the\nentrance points of networks. Cisco IOS Software provides a set of\nsecurity features that allow the configuration of a firewall policy\nto match an organization\u0027s requirements. \n\nThe vulnerabilities described in this advisory affect the Zone-Based\nFirewall feature. The Zone-Based Policy Firewall (also known as\nZone-Policy Firewall or ZFW) updates the firewall configuration from\nthe older interface-based model to a more flexible, more easily\nunderstood zone-based model. Interfaces are assigned to zones, and\ninspection policy is applied to traffic moving between the zones. \nInter-zone policies offer considerable flexibility and granularity,\nso different inspection policies can be applied to multiple host\ngroups connected to the same router interface. Only traffic destined to an IP address configured on the\ndevice can trigger the vulnerability; transit traffic is not an\nexploit vector. \n\nThis vulnerability is documented in Cisco bug ID CSCto89536 \nand has been assigned the Common Vulnerabilities and Exposures \n(CVE) identifier CVE-2012-1310. \n\nMemory Leak in HTTP Inspection\n+---------------------------------------------\n\nThe HTTP Inspection Engine feature allows users to configure their\nCisco IOS Firewall to detect and filter HTTP connections-such as\ntunneling over port 80, unauthorized request methods, and non-HTTP\ncompliant file transfers-that are not authorized within the scope of\nthe security policy configuration. Transit HTTP traffic is an exploit vector. \n\nThis vulnerability is documented in Cisco bug ID CSCtq36153 \nand has been assigned CVE ID CVE-2012-0387. \n\nMore information on HTTP inspection is available at:\nhttp://www.cisco.com/en/US/docs/ios/12_3t/12_3t14/feature/guide/gt_fwapc.html\n\nMemory Leak in H.323 Inspection\n+---------------------------------------------\nH.323 is the ITU standard for real-time multimedia communications and\nconferencing over packet-based (IP) networks. \nTransit H.323 traffic is an exploit vector. \n\nThis vulnerability is documented in Cisco bug ID CSCtq45553 \nand has been assigned the CVE ID CVE-2012-0388. \n\nMore information on H.323 inspection is available at: \nhttp://www.cisco.com/en/US/docs/ios-xml/ios/sec_data_zbf/configuration/15-2mt/fw-h323-v3v4-sup.html\n\nMemory Leak in SIP Inspection\n+---------------------------------------------\nSIP is a popular signaling protocol that is used to manage voice and\nvideo calls across IP networks, such as the Internet. SIP is\nresponsible for handling all aspects of call setup and termination. \nVoice and video are the most popular types of sessions that SIP\nhandles, but the protocol has the flexibility to accommodate other\napplications that require call setup and termination. SIP call\nsignaling can use UDP (port 5060), TCP (port 5060), or Transport\nLayer Security (TLS; TCP port 5061) as the underlying transport\nprotocol. Transit SIP traffic is an exploit vector. \n\nThis vulnerability is documented in Cisco bug ID CSCti46171 \nand has been assigned CVE ID CVE-2012-1315. \n\nMore information on SIP inspection is available at: \nhttp://www.cisco.com/en/US/docs/ios/security/configuration/guide/sec_sip_alg_aic.html\n\nMemory Leak Detection\n+---------------------------------------------\nDetected memory leaks can be viewed using the command show memory\ndebug leaks chunks in privileged EXEC mode, as shown in the following\nexample:\n\n Router# show memory debug leaks chunks \n\n Adding blocks for GD... I/O memory Address Size Alloc_pc PID\n Alloc-Proc Name Chunk Elements:\n AllocPC Address Size Parent Name Processor memory Address Size\n Alloc_pc PID Alloc-Proc Name\n 4733113C 188 419CB164 129 IP Input FW h225 tpkt\n\nThe previous example shows a memory leak in the process FW h225 tpkt. \n\nCaution: All show memory debug commands must be used on customer\nnetworks only to diagnose the router for memory leaks when memory\ndepletion is observed. These commands may cause high CPU utilization\nand may cause time-sensitive protocols to flap. These commands are\nrecommended to be used in maintenance windows. \n\nVulnerability Scoring Details\n=============================\n\nCisco has scored the vulnerabilities in this advisory based on the\nCommon Vulnerability Scoring System (CVSS). The CVSS scoring in this\nsecurity advisory is in accordance with CVSS version 2.0. \n\nCVSS is a standards-based scoring method that conveys vulnerability\nseverity and helps organizations determine the urgency and priority\nof a response. \n\nCisco has provided a base and temporal score. Customers can also\ncompute environmental scores that help determine the impact of the\nvulnerability in their own networks. \n\nCisco has provided additional information regarding CVSS at the\nfollowing link:\n\nhttp://www.cisco.com/web/about/security/intelligence/cvss-qandas.html\n\nCisco has also provided a CVSS calculator to compute the\nenvironmental impact for individual networks at the following link:\n\nhttp://intellishield.cisco.com/security/alertmanager/cvss\n\n\n* Memory Leak associated with crafted IP packets\n\nCVSS Base Score - 7.8\n Access Vector - Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - None\n Integrity Impact - None\n Availability Impact - Complete\n\nCVSS Temporal Score - 6.4\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n* Memory Leak in HTTP inspection\n\nCVSS Base Score - 7.8\n Access Vector - Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - None\n Integrity Impact - None\n Availability Impact - Complete\n\nCVSS Temporal Score - 6.4\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n* Memory Leak in H.323 inspection\n\nCVSS Base Score - 7.8\n Access Vector - Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - None\n Integrity Impact - None\n Availability Impact - Complete\n\nCVSS Temporal Score - 6.4\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n\n* Memory Leak in SIP Inspection\n\nCVSS Base Score - 7.8\n Access Vector - Network\n Access Complexity - Low\n Authentication - None\n Confidentiality Impact - None\n Integrity Impact - None\n Availability Impact - Complete\n\nCVSS Temporal Score - 6.4\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n\nImpact\n======\n\nSuccessful exploitation of these vulnerabilities may result in a\nreload of the affected device. Repeated exploit attempts may result\nin a sustained denial of service (DoS) attack. \n\nSoftware Versions and Fixes\n===========================\n\nWhen considering software upgrades, customers are advised to consult\nthe Cisco Security Advisories and Responses archive at:\nhttp://www.cisco.com/go/psirt and review subsequent advisories to determine\nexposure and a complete upgrade solution. \n\nIn all cases, customers should ensure that the devices to be upgraded\ncontain sufficient memory and confirm that current hardware and\nsoftware configurations will continue to be supported properly by the\nnew release. If the information is not clear, customers are advised\nto contact the Cisco Technical Assistance Center (TAC) or their\ncontracted maintenance providers. If a particular train is vulnerable, the\nearliest releases that contain the fix are listed in the First Fixed\nRelease column. The First Fixed Release for All Advisories in the\nMarch 2012 Bundled Publication column lists the earliest possible\nreleases that correct all the published vulnerabilities in the Cisco\nIOS Software Security Advisory bundled publication. Cisco recommends\nupgrading to the latest available release, where possible.

|\n| | 15.2(2)T1 | Available on |\n| | | 30-MAR-12 |\n+------------------------------------------+\n\n* Cisco Catalyst 3550 Series Switches support the Internet Key\nExchange (IKE) feature and are vulnerable to Cisco bug ID CSCts38429\nwhen the devices are running Layer 3 images; however, this product\nreached the End of Software Maintenance milestone. Cisco 3550 Series\nSMI Switches that are running Layer 2 images do not support IKE and\nare not vulnerable. No other Cisco devices that run 12.2SE-based\nsoftware are vulnerable. \n\nFor a mapping of Cisco IOS XE Software releases to Cisco IOS Software\nreleases, refer to Cisco IOS XE 2 Release Notes, Cisco IOS XE 3S\nRelease Notes, and Cisco IOS XE 3SG Release Notes. \n\n\n\nWorkarounds\n===========\n\nThere are no workarounds that mitigate the vulnerabilities described\nin this advisory. \n\nObtaining Fixed Software\n========================\n\nCisco has released free software updates that address the\nvulnerabilities described in this advisory. Prior to deploying\nsoftware, customers are advised to consult their maintenance\nproviders or check the software for feature set compatibility and\nknown issues that are specific to their environments. \n\nCustomers may only install and expect support for feature sets they\nhave purchased. By installing, downloading, accessing, or otherwise\nusing such software upgrades, customers agree to follow the terms of\nthe Cisco software license at:\nhttp://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html\nor as set forth at http://www.cisco.com/public/sw-center/sw-usingswc.shtml\n\nDo not contact psirt@cisco.com or security-alert@cisco.com for\nsoftware upgrades. \n\nCustomers with Service Contracts\n+-------------------------------\n\nCustomers with contracts should obtain upgraded software through\ntheir regular update channels. For most customers, upgrades should be\nobtained through the Software Center on Cisco.com at:\nhttp://www.cisco.com\n\nCustomers Using Third-Party Support Organizations\n+------------------------------------------------\n\nCustomers with Cisco products that are provided or maintained through\nprior or existing agreements with third-party support organizations,\nsuch as Cisco Partners, authorized resellers, or service providers,\nshould contact that organization for assistance with the appropriate\ncourse of action. \n\nThe effectiveness of any workaround or fix depends on specific\ncustomer situations, such as product mix, network topology, traffic\nbehavior, and organizational mission. Because of the variety of\naffected products and releases, customers should consult their\nservice providers or support organizations to ensure that any applied\nworkaround or fix is the most appropriate in the intended network\nbefore it is deployed. \n\nCustomers Without Service Contracts\n+----------------------------------\n\nCustomers who purchase directly from Cisco but do not hold a Cisco\nservice contract and customers who make purchases through third-party\nvendors but are unsuccessful in obtaining fixed software through\ntheir point of sale should obtain upgrades by contacting the Cisco\nTechnical Assistance Center (TAC):\n\n * +1 800 553 2447 (toll free from within North America)\n * +1 408 526 7209 (toll call from anywhere in the world)\n * e-mail: tac@cisco.com\n\nCustomers should have the product serial number available and be\nprepared to provide the URL of this advisory as evidence of\nentitlement to a free upgrade. Customers without service contracts\nshould request free upgrades through the TAC. \n\nRefer to Cisco Worldwide Contacts at:\nhttp://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html \nfor additional TAC contact information, including localized telephone \nnumbers, instructions, and e-mail addresses for support in various languages. \n\nExploitation and Public Announcements\n=====================================\n\nThe Cisco Product Security Incident Response Team (PSIRT) is not\naware of any public announcements or malicious use of the\nvulnerabilities that are described in this advisory. \n\nThese vulnerabilities were discovered by Cisco during normal internal\nsecurity testing. \n\nStatus of This Notice: Final\n\nTHIS DOCUMENT IS PROVIDED ON AN \"AS IS\" BASIS AND DOES NOT IMPLY ANY\nKIND OF GUARANTEE OR WARRANTY, INCLUDING THE WARRANTIES OF\nMERCHANTABILITY OR FITNESS FOR A PARTICULAR USE.
