This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Cerulean Studios Trillian Pro. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the header parsing code for the msn protocol. When processing the X-MMS-IM-FORMAT header, certain attributes are copied into a buffer located on the stack without any length verification which can eventually lead to code execution with the privileges of the user that is running the application.
