Revision Note: V1.1 (May 13, 2014): V1.1 (May 13, 2014): Corrected the update replacement for the Microsoft Office 2010 (proofing tools) (2878284) update.
Summary: This security update resolves two privately reported vulnerabilities in Microsoft Office. The most severe vulnerability could allow remote code execution if a user opens an Office 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 current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.
