This script is Copyright (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

A browser enhancement on the remote Mac OS X host could allow
arbitrary code execution.

Description :

The version of Microsoft Silverlight installed on the remote host
reportedly does not properly use unmanaged objects, which could allow
a malicious web application to access memory in an unsafe manner.

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.
