Detailsinfo

A vulnerability, which was classified as critical, was found in Cisco TelePresence TC and TE (Unified Communication Software). This affects an unknown function of the component SIP Processing Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Heap-based buffer overflow in Cisco TelePresence TC Software 4.x through 6.x before 6.0.1 and TE Software 4.x and 6.0.x before 6.0.2 allows remote attackers to execute arbitrary code via crafted SIP packets, aka Bug ID CSCud81796.

The weakness was published 04/30/2014 with Cisco as cisco-sa-20140430-tcte as confirmed advisory (Website). The advisory is shared at tools.cisco.com.
