VERIFY ADVISORY:
http://secunia.com/advisories/18835/

CRITICAL:
Highly critical

IMPACT:
System access

DESCRIPTION:
A vulnerability has been reported in Windows Media Player, which can
be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error within the
processing of bitmap files (.bmp) and can be exploited to cause a
buffer overflow via a specially crafted bitmap file.

Successful exploitation allows execution of arbitrary code when a
user e.g. visits a malicious web site, opens a malicious bitmap file
(Windows Media Player is not the default handler for bitmap files),
or opens a file (e.g. Word document) containing a malicious Windows
Media Player (.wmp) image.

The following supported products and product combinations are NOT
vulnerable:
* Windows Media Player 6.4
* Windows Media Player 10 on Windows Server 2003 SP1
