Published: | Updated:

Version: 1.1

General Information

Executive Summary

This security update resolves a privately reported vulnerability in Visual Studio Team Foundation Server. The vulnerability could allow elevation of privilege if a user clicks a specially crafted link in an email message or browses to a webpage that is used to exploit the vulnerability. In all cases, however, an attacker would have no way to force users to perform these actions. Instead, an attacker would have to convince users to visit a website, typically by getting them to click a link in an email message or Instant Messenger message that takes them to the attacker's website.

This security update is rated Important for all supported editions of Microsoft Visual Studio Team Foundation Server 2010. For more information, see the subsection, Affected and Non-Affected Software, in this section.
