Apple QuickTime RTSP Buffer Overflow

Disclosed November 23, 2007    No Patch Available

Vulnerability Description:

A stack-based buffer overflow occurs when processing a malformed RTSP server response. If the attacker develops a malicious RTSP server that is able to deliver a very long ‘Content-Type’ field, the QuickTime client that connects to this server over the RTSP protocol can then be exploited. This process can be further "automated" by launching the attack from within an HTML file, which makes it easier to trick vulnerable users into connecting to a malicious RTSP server.

QuickTime 7.3 and earlier
