Microsoft Security Bulletin MS08-069  Critical

Vulnerabilities in Microsoft XML Core Services Could Allow Remote Code 
Execution (955218)

   Published: November 11, 2008

   Version: 1.0

General Information

Executive Summary

   This security update resolves several vulnerabilities in Microsoft XML 
   Core Services. The most severe vulnerability could allow remote code 
   execution if a user viewed a specially crafted Web page using Internet 
   Explorer. 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.

   This security update is rated Critical for Microsoft XML Core Services 
   3.0 and Important for Microsoft XML Core Services 4.0, Microsoft XML Core 
   Services 5.0, and Microsoft XML Core Services 6.0.

   The security update addresses the vulnerabilities by modifying the way 
   that Microsoft XML Core Services parses XML content, handles external 
   document type definitions (DTD), and sets HTTP request fields.

   Recommendation. Microsoft recommends that customers apply the update 
   immediately.
