Microsoft Security Bulletin MS12-029 - Critical
Vulnerability in Microsoft Word Could Allow Remote Code Execution (2680352)
Published: | Updated:
This security update resolves a privately reported vulnerability in Microsoft Office. The vulnerability could allow remote code execution if a user opens a specially crafted RTF file. An attacker who successfully exploited the vulnerability could gain the same user rights as the current 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 Critical for all supported editions of Microsoft Word 2007. This security update is also rated Important for all supported editions of Microsoft Word 2003, Microsoft Office 2008 for Mac, and Microsoft Office for Mac 2011; and all supported versions of Microsoft Office Compatibility Pack. For more information, see the subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerabilities by modifying the way that Microsoft Office parses RTF-formatted data. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
