Microsoft Security Bulletin MS10-055 - Critical

Vulnerability in Cinepak Codec Could Allow Remote Code Execution (982665)

Version: 1.0

General Information

Executive Summary

  This security update resolves a privately reported vulnerability in Cinepak 
  Codec. The vulnerability could allow remote code execution if a user opens a 
  specially crafted media file or receives specially crafted streaming content 
  from a Web site or any application that delivers Web content. 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 all supported editions of Windows 
  XP, Windows Vista, and Windows 7. For more information, see the subsection, 
  Affected and Non-Affected Software, in this section.

  The security update addresses the vulnerability by correcting the manner in 
  which the Cinepak code decompresses media files. For more information about 
  the vulnerability, see the Frequently Asked Questions (FAQ) subsection for 
  the specific vulnerability entry under the next section, Vulnerability 
  Information.

Affected Software

  Windows XP Service Pack 3
  Windows XP Professional x64 Edition Service Pack 2
  Windows Vista Service Pack 1 and Windows Vista Service Pack 2
  Windows Vista x64 Edition Service Pack 1 and Windows Vista x64 Edition 
    Service Pack 2
  Windows 7 for 32-bit Systems
  Windows 7 for x64-based Systems

Vulnerability Information

Cinepak Codec Decompression Vulnerability - CVE-2010-2553

  A remote code execution vulnerability exists in the way the Cinepak codec 
  handles supported format files. This vulnerability could allow code 
  execution if a user opened a specially crafted media file. If a user is 
  logged on with administrative user rights, 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.
