Detail

Severity Rating: Important

Revision Note: V1.1 (August 10, 2011): Corrected the restart requirements for the update on all affected operating systems.

Summary: This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a legitimate Excel file (such as a .xlsx file) that is located in the same network directory as a specially crafted library file. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on 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
74408 Microsoft Windows Data Access Tracing Component Path Subversion Arbitrary DLL...

Windows Data Access Tracing Component 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 Excel 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.
