Severity Rating: Important
Revision Note: V1.0 (March 13, 2012): Bulletin published.
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.
