Microsoft Security Bulletin MS11-055 - Important
Vulnerability in Microsoft Visio Could Allow Remote Code Execution (2560847)
This security update resolves a publicly disclosed vulnerability in Microsoft Visio. The vulnerability could allow remote code execution if a user opens a legitimate Visio 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.
This security update is rated Important for Microsoft Visio 2003 Service Pack 3. 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 Microsoft Visio loads external libraries.
