09.256.2011 - MS11-072 - Important : Vulnerabilities in Microsoft Excel Could Allow Remote Code Execution (2587505) - Version: 1.0

Severity Rating: Important Revision Note: V1.0 (September 13, 2011): Bulletin published. 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. See the section, Frequently Asked Questions (FAQ) Related to This Security Update, for more information about how the Office File Validation feature can be configured to block the attack vectors. - View Microsoft Security Bulletin MS11-072 - View Microsoft Knowledge Base Article - on: 1. - Visit Microsoft Corporation
