DESCRIPTION:
iDefense Labs has reported a vulnerability 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
decoding of PNG (Portable Network Graphics) image file chunks. This
can be exploited to cause a stack-based buffer overflow via a
specially crafted PNG image when a user opens a malicious WMZ file or
visits a malicious web site.

Successful exploitation allows execution of arbitrary code.

SOLUTION:
Apply patches.
