Microsoft Security Bulletin MS11-001 - Important

Vulnerability in Windows Backup Manager Could Allow Remote Code Execution
(2478935)

   Published: January 11, 2011

   Version: 1.0

General Information

Executive Summary

   This security update resolves a publicly disclosed vulnerability in
   Windows Backup Manager. The vulnerability could allow remote code
   execution if a user opens a legitimate Windows Backup Manager file
   that is located in the same network directory 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 the
   legitimate file from that location, which in turn could cause Windows
   Backup Manager to load the specially crafted library file.

   This security update is rated Important for all supported editions of
   Windows Vista. For more information, see the subsection, Affected and
   Non-Affected Software, in this section.

Affected Software

   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

Vulnerability Information

Backup Manager Insecure Library Loading Vulnerability - CVE-2010-3145

   A remote code execution vulnerability exists in the way that the
   Microsoft Windows Backup Manager handles the loading of DLL files. 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.
