Severity Rating: Critical
Revision Note: V1.1 (May 16, 2012): Added a link to Microsoft Knowledge Base Article 2681578 under Known Issues in the Executive Summary. Also added Microsoft .NET Framework 1.1 Service Pack 1 to the Non-Affected Software table and corrected the update replacement information for Microsoft Office. These were informational changes only. There were no changes to the security update files or detection logic.
Summary: This security update resolves three publicly disclosed vulnerabilities and seven privately reported vulnerabilities in Microsoft Office, Microsoft Windows, the Microsoft .NET Framework, and Microsoft Silverlight. The most severe of these vulnerabilities could allow remote code execution if a user opens a specially crafted document or visits a malicious webpage that embeds TrueType font files. An attacker would have no way to force users to visit a malicious website. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes them to the attacker’s website.
