Microsoft Security Bulletin MS10-051 - Critical

Vulnerability in Microsoft XML Core Services Could Allow Remote Code Execution 
(2079403)

Version: 1.0

General Information

Executive Summary

  This security update resolves a privately reported vulnerability in Microsoft 
  XML Core Services. The vulnerability could allow remote code execution if a 
  user viewed a specially crafted Web page using Internet Explorer. An attacker
  would have no way to force users to visit these Web sites. Instead, an 
  attacker would have to persuade users to visit the Web site, typically by 
  getting them to click a link in an e-mail message or Instant Messenger 
  message that takes users to the attacker's Web site.

  This security update is rated Critical for Microsoft XML Core Services 3.0 on 
  all supported releases of Windows XP, Windows Vista, and Windows 7; and 
  Moderate for Microsoft XML Core Services 3.0 on all supported releases of 
  Windows Server 2003, Windows Server 2008, and Windows Server 2008 R2. For 
  more information, see the subsection, Affected and Non-Affected Software, in 
  this section.

  The security update addresses the vulnerability by ensuring that HTTP 
  responses are handled correctly by MSXML. For more information about the 
  vulnerability, see the Frequently Asked Questions (FAQ) subsection for the 
  specific vulnerability entry under the next section, Vulnerability 
  Information.

Vulnerability Information

Msxml2.XMLHTTP.3.0 Response Handling Memory Corruption Vulnerability - 
CVE-2010-2561

  A remote code execution vulnerability exists in the way that Microsoft XML 
  Core Services handles HTTP responses. The vulnerability could allow remote 
  code execution if a user browses a Web site that contains specially crafted 
  content or opens specially crafted HTML e-mail. 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.
