Microsoft MSN Messenger GIF Image Processing Remote Buffer Overflow Vulnerability

Microsoft MSN Messenger GIF Image Processing Remote Buffer Overflow Vulnerability

Microsoft MSN Messenger is prone to a remote buffer-overflow vulnerability when handling malformed Graphic Interchange Format (GIF) images. This may allow an attacker to gain unauthorized access to an affected computer by executing arbitrary code, reportedly resulting in system-level compromise. Specially crafted emoticons or display pictures are likely to be used in a client-to-client attack.

Other attack vectors may exist as well.

MSN Messenger 6.2 and MSN Messenger 7.0 beta are vulnerable.
