Reference : http://www.securityfocus.com/bid/18322


A remote code execution vulnerability exists in the

Graphics Rendering Engine because of the way that it

handles Windows Metafile (WMF) images.

An attacker could exploit this by placing a specially

crafted WMF or EMF image on a webpage, or by sending

the image as an attachment in an e-mail. The exploit

is triggered by viewing the specially crafted image

file. No user interaction is required.

An attacker who successfully exploited this vulnerability

could take complete control of the affected system.


A heap overflow vulnerability exists in the WMF

PolyPolygon function, because of an unchecked user-

supplied parameter.

<Details witheld for 30 days. Full disclosure on

The manner of the heap corruption is under user control,

which can result in the execution of arbitrary code.
