Cisco TelePresence TC and TE Software are affected by the following vulnerabilities: Six Session Initiation Protocol (SIP) denial of service vulnerabilities Cisco TelePresence TC and TE Software DNS Buffer Overflow Vulnerability Cisco TelePresence TC and TE Software Input Validation Vulnerability Cisco TelePresence TC and TE Software tshell Command Injection Vulnerability Cisco TelePresence TC and TE Software Heap Overflow Vulnerability Cisco TelePresence TC and TE Software U-Boot Buffer Overflow Vulnerability Cisco TelePresence TC and TE Software Unauthenticated Serial Port Access Vulnerability Cisco TelePresence TC H.225 Denial of Service Vulnerability Successful exploitation of these vulnerabilities could allow an attacker to cause the affected system to reload, execute arbitrary commands or obtain privileged access to the affected system. Note: This security advisory does not provide information about the OpenSSL TLS Heartbeat Read Overrun Vulnerability identified by CVE-2014-0160 (also known as Heartbleed). For additional information on Cisco products affected by the Heartbleed vulnerability, refer to the Cisco Security Advisory available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20140409-heartbleed Cisco has released software updates that address these vulnerabilities. There are no workarounds that mitigate these vulnerabilities. This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20140430-tcte
A vulnerability in the H.225 code of Cisco TelePresence TC Software could allow an unauthenticated, remote attacker to cause the
affected system to exhaust the available memory and to reload.
The
vulnerability is due to the improper handling of crafted or malformed H.225
packets. An attacker could exploit this vulnerability by sending
crafted packets to the affected system.
When considering software upgrades, customers are advised to consult the Cisco Security Advisories, Responses, and Notices 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.
