MS11-078: Vulnerability in Microsoft Silverlight Could Allow Remote Code Execution (2604930) (Mac OS X)

High Nessus Plugin ID 58094


A multimedia application framework installed on the remote Mac OS X host is affected by a remote code execution vulnerability.


The version of Microsoft Silverlight installed on the remote host reportedly does not properly restrict inheritance within classes.

An attacker may be able to leverage this vulnerability to execute arbitrary code on the affected system if a user on it can be tricked into viewing a specially crafted web page using a web browser that can run Silverlight applications.


Microsoft has released a patch for Silverlight 4.
