Comment: Microsoft have published the following work around for this
         vulnerability:
         
         Microsoft Forefront Security for Exchange Server, Microsoft
         Forefront Security for SharePoint, and Microsoft Antigen supports
         multiple engines in addition to the Microsoft Malware Protection
         Engine on a single system. If multiple engines are available on an
         affected system, administrators can disable the Microsoft Malware
         Protection Engine as a workaround, until the Microsoft Malware
         Protection Engine can be updated. Before disabling the Microsoft
         Malware Protection Engine, administrators should ensure they have
         installed the latest virus signatures for any third party engine.

Vulnerability Details

Microsoft Malware Protection Engine Vulnerability - CVE-2006-5270:

   A remote code execution vulnerability exists in the Microsoft Malware
   Protection Engine because of the way that it parses Portable Document
   Format (PDF) files. An attacker could exploit the vulnerability by
   constructing a specially crafted PDF File that could potentially allow
   remote code execution when the target computer system receives, and
   the Microsoft Malware Protection Engine scans, the PDF file.
