Microsoft Security Bulletin MS11-042 MS11-042 - Critical : Vulnerabilities in Distributed File System Could Allow Remote Code Execution (2535512) - Version: 1.1 Severity Rating: Critical Revision Note: V1.1 (June 14, 2011): Moved Windows 7 for 32-bit Systems Service Pack 1, Windows 7 for x64-based Systems Service Pack 1, Windows Server 2008 R2 for x64-based Systems Service Pack 1, and Windows Server 2008 R2 for Itanium-based Systems Service Pack 1 from the affected software table to the non-affected software table. This is an informational change only. There were no changes to the security update files or detection logic. Summary: This security update resolves two privately reported vulnerabilities in the Microsoft Distributed File System (DFS). The more severe of these vulnerabilities could allow remote code execution when an attacker sends a specially crafted DFS response to a client-initiated DFS request. An attacker who successfully exploited this vulnerability could execute arbitrary code and take complete control of an affected system.
