TITLE:
Winamp ID3v2 Tag Handling Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA16077

VERIFY ADVISORY:
http://secunia.com/advisories/16077/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Winamp 5.x
http://secunia.com/product/3021/

DESCRIPTION:
Leon Juranic has reported a vulnerability in Winamp, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the handling
of ID3v2 tags and can be exploited to cause a buffer overflow via
e.g. a MP3 file containing an overly long string in the "Artist"
field.

Successful exploitation allows execution of arbitrary code, but
requires some user interaction (e.g. that the user adds a malicious
MP3 file to a playlist and then plays the file).

The vulnerability has been reported in versions 5.03a, 5.09, and
5.091. Other versions may also be affected.

SOLUTION:
The vendor will reportedly issue a fixed version soon.

PROVIDED AND/OR DISCOVERED BY:
Leon Juranic, LSS Security Team.
