DESCRIPTION:
Two vulnerabilities have been reported in Microsoft Windows, which
can be exploited by malicious people to compromise a vulnerable
system.

1) A boundary error exists in the Graphics Rendering Engine when
rendering certain malformed Windows Metafile (WMF) and Enhanced
Metafile (EMF) image files. This can be exploited to execute
arbitrary code on a user's system via a specially crafted WMF/EMF
file.

2) A boundary error exists in the rendering of certain malformed
Windows Metafile (WMF) image files. This can be exploited to execute
arbitrary code on a user's system via a specially crafted WMF file.

Vulnerability #1 and #2 reportedly affects any program that renders
the affected image types and can be exploited by e.g. tricking the
user to open a malicious WMF/EMF file, or to view a folder that
contains the image. The vulnerabilities are also reportedly
exploitable by embedding the image in an Office document, or by
convincing the user to view an HTML email in Outlook containing an
image attachment, or via a malicious web site.

SOLUTION:
Apply patches.
