Microsoft Security Bulletin MS12-022 - Important
Vulnerability in Expression Design Could Allow Remote Code Execution (2651018)

Published: Tuesday, March 13, 2012 | Updated: Wednesday, March 14, 2012

Version: 1.1
General Information
Executive Summary

This security update resolves one privately reported vulnerability in Microsoft Expression Design. The vulnerability could allow remote code execution if a user opens a legitimate file (such as an .xpr or .DESIGN file) that is located in the same network directory as a specially crafted dynamic link library (DLL) file. Then, while opening the legitimate file, Microsoft Expression Design could attempt to load the DLL file and execute any code it contained. For an attack to be successful, a user must visit an untrusted remote file system location or WebDAV share and open a legitimate file (such as an .xpr or .DESIGN file) from this location that is then loaded by a vulnerable application.

This security update is rated Important for all supported releases of Microsoft Expression Design. 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 Microsoft Expression Design 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.
