Microsoft Security Bulletin MS12-021 - Important
Vulnerability in Visual Studio Could Allow Elevation of Privilege (2651019)

Published: Tuesday, March 13, 2012

Version: 1.0
General Information
Executive Summary

This security update resolves one privately reported vulnerability in Visual Studio. The vulnerability could allow elevation of privilege if an attacker places a specially crafted add-in in the path used by Visual Studio and convinces a user with higher privileges to start Visual Studio. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability. The vulnerability could not be exploited remotely or by anonymous users.

This security update is rated Important for all supported editions of Microsoft Visual Studio 2008 and Microsoft Visual Studio 2010. 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 Visual Studio restricts where add-ins are loaded. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
