Apple QuickTime RTSP Response Header Content-Type Remote Stack Based Buffer Overflow Vulnerability

Apple QuickTime is prone to a remote buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied input before copying it to an insufficiently sized stack-based memory buffer.

This issue occurs when handling specially crafted RTSP Response headers.

Attackers can leverage this issue to execute arbitrary machine code in the context of the user running the affected application. Successful exploits will compromise the application and possibly the underlying computer. Failed attacks will likely cause denial-of-service conditions.

QuickTime 7.3 is vulnerable to this issue; other versions may also be affected.

UPDATE (December 4, 2007): Attackers are exploiting this issue through the Second Life Viewer to steal Linden dollars from unsuspecting victims.
