MS11-031: Vulnerability in JScript and VBScript Scripting Engines Could Allow Remote Code Execution (2514666)

This script is Copyright (C) 2011-2014 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 version of the JScript and VBScript scripting engines
contains an integer overflow vulnerability that can occur when the
scripting engines process a script in a web page and attempt to
reallocate memory while decoding the script.

If an attacker can trick a user on the affected system into visiting a
malicious website, this issue could be leveraged to execute arbitrary
code subject to the user's privileges.
