Detail

Revision Note: 1.0 (December 14, 2010): Bulletin published.Summary: This security update resolves a publicly disclosed vulnerability in Windows Media Encoder. The vulnerability could allow remote code execution if an attacker convinces a user to open a legitimate Windows Media Profile (.prx) 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 a document from this location that is then loaded by a vulnerable application.

Id Description
67784 Microsoft Windows Media Encoder Path Subversion Arbitrary DLL Injection Code ...

Microsoft Windows Media Encoder is prone to a flaw in the way it loads dynamic-link libraries (e.g. wmerrorDAN.dll, wininetDAN.dll). The program uses a fixed path to look for specific files or libraries. This path includes directories that may not be trusted or under user control. By placing a custom version of the file or library in the path, the program will load it before the legitimate version. This allows an attacker to inject custom code that will be run with the privilege of the program or user executing the program. This can be done by tricking a user into opening a Windows Media Profile (.prx) or Windows Media Encoder Session (.wme) file from the local file system or a USB drive in some cases. This attack can be leveraged remotely in some cases by placing the malicious file or library on a network share or extracted archive downloaded from a remote source.
