  DESCRIPTION

SIPfoundry is an international software community dedicated to accelerating the adoption of SIP (Session Initiation Protocol)-based VoIP solutions. One of SIPfoundry's products, the sipXtapi library, is used by multiple cross-platform VoIP applications. This library contains a buffer overflow that can be triggered by sending a "CSeq" SIP header field larger than 24 bytes. An attacker can exploit the flaw to execute arbitrary code with the privileges of the user running the affected application. Note that several common user applications, including AOL's Triton messaging application, are compiled using vulnerable versions of the library.
