Microsoft Security Bulletin MS10-095 - Important
Vulnerability in Microsoft Windows Could Allow Remote Code Execution (2385678)
Version: 1.0
General Information
Executive Summary
This security update resolves a privately reported vulnerability in
Microsoft Windows. The vulnerability could allow remote code execution if
a user opens a file type such as .eml and .rss (Windows Live Mail) or
.wpost (Microsoft Live Writer) located in the same network folder as a
specially crafted library file. For an attack to be successful, a user must
visit an untrusted remote file system location or WebDAV share and open a
document from this location that is then loaded by a vulnerable application.
This security update is rated Important for all supported editions of
Windows 7 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 correcting the manner in
which the Windows BranchCache loads external libraries. 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 7 for 32-bit Systems
Windows 7 for x64-based Systems
Windows Server 2008 R2 for x64-based Systems*
Windows Server 2008 R2 for Itanium-based Systems
*Server Core installation affected.
Vulnerability Information
BranchCache Insecure Library Loading Vulnerability - CVE-2010-3966
A remote code execution vulnerability exists in the way that Microsoft
Windows opens specific files on platforms that do not support the
BranchCache functionality. 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.
