                Millennium Edition
Severity      : Remotely exploitable arbitrary code execution

                and KB918547)
CVE Number    : CVE-2006-2376
Reference     : http://www.securityfocus.com/bid/18322


Overview:

        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.


Details:

        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 
        July 11, 2006>

        The manner of the heap corruption is under user control,
        which can result in the execution of arbitrary code.


Vendor Response:

        The above vulnerability was addressed for the affected
        platforms via Microsoft Security Bulletin MS06-026. If
        there are any further questions about this statement,
        please contact secure@...rosoft.com.


Recommendation:

        Follow your organization's testing procedures before
        applying patches or workarounds.  Customers should apply
        Microsoft's update as soon as possible.
