TITLE:
Apple QuickTime RTSP "Content-Type" Header Buffer Overflow

SECUNIA ADVISORY ID:
SA27755

VERIFY ADVISORY:
http://secunia.com/advisories/27755/

CRITICAL:
Extremely critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Apple QuickTime 7.x
http://secunia.com/product/5090/

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.

NOTE: A working exploit is publicly available.

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