Detail

Revision Note: V1.0 (November 13, 2012): Bulletin published.

Summary: This security update resolves four privately reported vulnerabilities in Microsoft Office. The vulnerabilities could allow remote code execution if a user opens a specially crafted Excel file with an affected version of Microsoft Excel. 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.
