Microsoft Security Bulletin MS12-030 - Important
Vulnerabilities in Microsoft Office Could Allow Remote Code Execution (2663830)
Published: Tuesday, May 08, 2012
Version: 1.0
General Information
Executive Summary
This security update resolves one publicly disclosed and five privately
reported vulnerabilities in Microsoft Office. The vulnerabilities could allow
remote code execution if a user opens a specially crafted Office file. An
attacker who successfully exploited these vulnerabilities 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 all supported editions of Microsoft
Excel 2003, Microsoft Excel 2007, Microsoft Office 2007, Microsoft Excel 2010,
Microsoft Office 2010, Microsoft Office 2008 for Mac, and Microsoft Office for
