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

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.
