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

high Nessus Plugin ID 61531

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.

Solution

Microsoft has released a set of patches for 64-bit editions of Windows XP, 2003, Vista, 2008, 7, and 2008 R2.
