Synopsis
========

Gaim contains a remotely exploitable buffer overflow vulnerability in
the MSN-protocol parsing code that may allow remote execution of
arbitrary code.

Description
===========

Sebastian Krahmer of the SuSE Security Team has discovered a remotely
exploitable buffer overflow vulnerability in the code handling MSN
protocol parsing.

Impact
