Vulnerabilities in Microsoft Excel Could Allow Remote Code Execution (2885080)
Published: Tuesday, October 08, 2013
Version: 1.0
General Information
Executive Summary
This security update resolves two privately reported vulnerabilities in
Microsoft Office. The vulnerabilities could allow remote code execution if a
user opens a specially crafted Office file with an affected version of
Microsoft Excel or other affected Microsoft Office software. An attacker who
successfully exploited the vulnerabilities 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 Important for all supported editions of
Microsoft Office 2007, Microsoft Office 2010, Microsoft Office 2013, Microsoft
Office 2013 RT, and Microsoft Office for Mac 2011. The update is also rated
