Microsoft Security Bulletin MS09-051 - Critical

Vulnerabilities in Windows Media Runtime Could Allow Remote Code Execution 
(975682)

Published: October 13, 2009

Version: 1.0

General Information

Executive Summary

  This security update resolves two privately reported vulnerabilities in 
  Windows Media Runtime. The vulnerabilities could allow remote code execution 
  if a user opened a specially crafted media file or received specially crafted 
  streaming content from a Web site or any application that delivers Web 
  content. An attacker who successfully exploited these vulnerabilities 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 DirectShow WMA Voice Codec, 
  Windows Media Audio Voice Decoder, and Audio Compression Manager on supported 
  editions of Microsoft Windows 2000; Windows XP; Windows Server 2003, except 
  for Itanium-based editions; Windows Vista; and Windows Server 2008, except 
  for Itanium-based editions. For more information, see the subsection, 
  Affected and Non-Affected Software, in this section.

  The security update addresses the vulnerabilities by changing the manner in 
  which the Windows Media Runtime processes ASF files and initializes functions 
  in compressed audio files. For more information about the vulnerabilities, 
  see the Frequently Asked Questions (FAQ) subsection for the specific 
  vulnerability entry under the next section, Vulnerability Information.

  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.

Vulnerability Information

Windows Media Runtime Voice Sample Rate Vulnerability - CVE-2009-0555

  A remote code execution vulnerability exists in Windows Media Player due 
  to the improper processing of specially crafted Advanced Systems Format 
  (ASF) files. An attacker could exploit the vulnerability by constructing a 
  specially crafted audio file that could allow remote code execution when 
  played using an affected version of Windows Media Player. An attacker who 
  successfully exploited this vulnerability could take complete control of an 
  affected system.
