Cisco TelePresence Video Communication Server extends the benefits of face-to-face video collaboration across networks and organizations by supporting any-to-any video and telepresence communications.
Software versions prior to X7.0.1 contain vulnerabilities that could cause a crash of the affected device and result in a DoS condition. These vulnerabilities are triggered by a crafted Session Initiation Protocol (SIP) packet that is sent to an affected device on either TCP and UDP ports 5060 or 5061.
These vulnerabilities are documented in Cisco bug ID CSCtr20426 (registered customers only) and CSCtq73319 (registered customers only), and have been assigned Common Vulnerability and Exposure (CVE) IDs CVE-2012-0330 and CVE-2012-0331, respectively.
-
There are no workarounds available that mitigate these vulnerabilities.
Additional mitigations that can be deployed on Cisco devices within the network are available in the Cisco Applied Intelligence companion document for this advisory: https://sec.cloudapps.cisco.com/security/center/content/CiscoAppliedMitigationBulletin/cisco-amb-20120229-vcs.
In order to improve the security posture of their installations, users are recommended to consult the Cisco TelePresence Hardening Guide, which is available at: http://www.cisco.com/web/about/security/intelligence/TP_Harden_Guide_wp.html.

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.
These vulnerabilities have been fixed in the X7.0.1 version of the software.
