Microsoft Security Bulletin MS11-091 - Important
Vulnerabilities in Microsoft Publisher Could Allow Remote Code Execution (2607702)

Published: Tuesday, December 13, 2011

Version: 1.0
General Information
Executive Summary

This security update resolves one publicly disclosed vulnerability and three privately reported vulnerabilities in Microsoft Office. The most severe vulnerabilities could allow remote code execution if a user opens a specially crafted Publisher file. An attacker who successfully exploited any of these vulnerabilities could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. 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 supported editions of Microsoft Publisher 2003 and Microsoft Publisher 2007. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the vulnerabilities by correcting the way that Microsoft Publisher parses specially crafted Publisher files. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
