ms11-042

MS11-042 is a critical security bulletin from Microsoft, released in June 2011, addressing two privately reported vulnerabilities in the Microsoft Distributed File System (DFS). The most severe vulnerability could allow remote code execution if an attacker sends a specially crafted DFS response to a client-initiated DFS request. Successful exploitation could enable an attacker to execute arbitrary code and take complete control of an affected system. The update applies to various Windows versions, with firewall best practices recommended to mitigate network-based attacks. This tag covers discussions and details about the bulletin, including revision notes and affected software.
