DESCRIPTION:
h07 has discovered a vulnerability in Apple QuickTime, which can be
exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a BOUNDARY error when processing
RTSP replies and can be exploited to CAUSE a stack-based buffer
overflow via a SPECIALLY crafted RTSP reply containing an overly long
"Content-Type" header.
Successful EXPLOITATION allows execution of arbitrary code and
requires that the user is e.g. tricked into opening a malicious QTL
file or visiting a malicious web site.
The vulnerability is confirmed in version 7.3. Other versions may
also be affected.

SOLUTION:
Do not browse untrusted websites, follow untrusted links, nor open
untrusted QTL files.
