CERT TA11-256A
Microsoft Security Bulletin MS11-072 MS11-072 - Important : Vulnerabilities in Microsoft Excel Could Allow Remote Code Execution (2587505) - Version: 1.1 Severity Rating: Important Revision Note: V1.1 (October 11, 2011): Announced a detection logic change for update KB2553094. There were no changes to the security update files. See the Update FAQ for details. Summary: This security update resolves five privately reported vulnerabilities in Microsoft Office. The vulnerabilities could allow remote code execution if a user opens a specially crafted Excel file. An attacker who successfully exploited any of 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. Installing and configuring Office File Validation (OFV) to prevent the opening of suspicious files blocks the attack vectors for exploiting the vulnerabilities described in CVE-2011-1986 and CVE-2011-1987.
