Revision Note: V1.1 (April 20, 2011): Corrected the bulletin replacement information for the Microsoft PowerPoint Web App update (KB2520047). This is an informational change only. There were no changes to the detection logic or the update files.
Summary: This security update resolves three privately reported vulnerabilities in Microsoft PowerPoint. The vulnerabilities could allow remote code execution if a user opens a specially crafted PowerPoint file. An attacker who successfully exploited any of these vulnerabilities could gain the same user rights as the local 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. The automated Microsoft Fix it solution for PowerPoint 2010, "Disable Edit in Protected View for PowerPoint 2010," available in Microsoft Knowledge Base Article 2501584, blocks the attack vectors for exploiting the vulnerabilities described in CVE-2011-0655 and CVE-2011-0656.
