Microsoft Security Bulletin MS09-052 - Critical

Vulnerability in Windows Media Player Could Allow Remote Code Execution 
(974112)

Published: October 13, 2009

Version: 1.0

General Information

Executive Summary

  This security update resolves a privately reported vulnerability in Windows 
  Media Player. The vulnerability could allow remote code execution if a 
  specially crafted ASF file is played using Windows Media Player 6.4. An 
  attacker who successfully exploited this vulnerability could gain the same 
  user rights as the local user. 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 Windows Media Player 6.4 
  when installed on all supported editions of Microsoft Windows 2000, Windows 
  XP, and Windows Server 2003.

  The security update addresses the vulnerability by correcting the manner in 
  which Windows Media Player 6.4 handles specially crafted ASF files. 

  Recommendation. The majority of customers have automatic updating enabled and 
  will not need to take any action because this security update will be 
  downloaded and installed automatically. Customers who have not enabled 
  automatic updating need to check for updates and install this update manually. 
  For information about specific configuration options in automatic updating, 
  see Microsoft Knowledge Base Article 294871.

  For administrators and enterprise installations, or end users who want to
  install this security update manually, Microsoft recommends that customers 
  apply the update immediately using update management software, or by checking
  for updates using the Microsoft Update service.
