-- Vulnerability Details:

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.
