Detail

Severity Rating: Important

Revision Note: V2.0 (November 8, 2011): Rereleased this bulletin to announce availability of an update for Windows 7 Embedded. No other update packages are affected by this rerelease.

Summary: This security update resolves a publicly disclosed vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a legitimate rich text format file (.rtf), text file (.txt), or Word document (.doc) that is located in the same network directory as a specially crafted dynamic link library (DLL) file. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. 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.

Id Description
75382 Microsoft Windows Shell Extensions Path Subversion Arbitrary DLL Injection Co...

Microsoft Windows is prone to a flaw in the way it loads dynamic-link libraries (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 .txt, .rtf or .doc 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.
