MS12-056: Vulnerability in JScript and VBScript Scripting Engines Could Allow Remote Code Execution (2706045)

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


Synopsis :

Arbitrary code can be executed on the remote host through the installed
JScript and VBScript scripting engines.

Description :

The installed versions of the JScript and VBScript scripting engines
contain an integer overflow vulnerability that can occur when the
scripting engines process a script in a web page and attempt to
calculate the size of an object in memory during a copy operation.

By tricking a user on the affected system into visiting a malicious web
site, an attacker may be able to exploit this issue to execute arbitrary
code subject to the user's privileges.
