DESCRIPTION:
cyanid-E has discovered a vulnerability in Microsoft Windows, which
can be exploited by malicious people to cause a DoS (Denial of
Service).

The vulnerability is caused due to a signedness error in the GDI
Client DLL library (gdi32.dll) when processing WMF files. This can be
exploited to crash an application using the vulnerable library (e.g.
explorer.exe) by tricking a user into viewing a specially crafted WMF
file.

The vulnerability has been confirmed on a fully patched Windows XP
SP2. Other versions may also be affected.

SOLUTION:
Grant only trusted users access to affected systems. Open trusted WMF
files only.

PROVIDED AND/OR DISCOVERED BY:
cyanid-E
