Executive Summary

   This security update resolves two privately reported vulnerabilities 
   that could allow remote code execution if a user opens a specially 
   crafted Word file. An attacker who successfully exploited either 
   vulnerability could take complete control of an affected system. An 
   attacker could then install programs; view, change, or delete data; or 
   create new accounts with full user rights.

Vulnerability Information

   Word Buffer Overflow Vulnerability - CVE-2009-0563

   A remote code execution vulnerability exists in the way that Microsoft 
   Office Word handles a specially crafted Word file that includes a 
   malformed record. An attacker who successfully exploited this 
   vulnerability could take complete control of an affected system. An 
   attacker could then install programs; view, change, or delete data; or 
   create new accounts with full user rights. Users whose accounts are 
   configured to have fewer user rights on the system could be less 
   impacted than users who operate with administrative user rights.
