MS11-078: Vulnerability in .NET Framework and Microsoft Silverlight Could Allow Remote Code Execution (2604930)

High Nessus Plugin ID 56452


The version of the .NET Framework installed on the remote host allows arbitrary code execution.


The remote Windows host is running a version of the Microsoft .NET Framework or Silverlight 4 that improperly restricts inheritance within classes. A remote attacker could exploit this issue by tricking a user into viewing a specially crafted web page, resulting in arbitrary code execution.


Microsoft has released a set of patches for the .NET Framework on Windows XP, 2003, Vista, 2008, 7, and 2008 R2.
