ZDI-08-054: Multiple Vendor libpurple MSN Protocol SLP Message Heap Overflow Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-08-054 August 28, 2008
The specific flaw exists in the implementation of the MSN protocol, specifically the handling of SLP messages. The function msn_slplink_process_msg() fails to properly validate an offset value specified in the SLP packet. By providing a specific value, an attacker can overflow a heap buffer resulting in arbitrary code execution.
