TITLE:
Apple QuickTime RTSP Reply Reason-Phrase Buffer Overflow

SECUNIA ADVISORY ID:
SA28423

VERIFY ADVISORY:
http://secunia.com/advisories/28423/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

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

DESCRIPTION:
Luigi Auriemma has reported a vulnerability in Apple QuickTime, which
potentially can be exploited by malicious people to compromise a
user's system.

The vulnerability is caused due to a boundary error when handling
RTSP replies and can be exploited to cause a buffer overflow via e.g.
sending a specially crafted reply containing an overly-long
"Reason-Phrase".

Successful exploitation may allow execution of arbitrary code, but
requires that the user is e.g. tricked into opening a malicious QTL
file or visiting a malicious web site.

The vulnerability is reported in version 7.3.1.70. Other versions may
also be affected.

SOLUTION:
Do not browse untrusted websites, open malicious .QTL files, or
follow untrusted links.

PROVIDED AND/OR DISCOVERED BY:
