Microsoft Security Bulletin MS14-011 - Critical

Vulnerability in VBScript Scripting Engine Could Allow Remote Code Execution 

Published Date: February 11, 2014

Version: 1.0

General Information

Executive Summary 

This security update resolves a privately reported vulnerability in the 
VBScript scripting engine in Microsoft Windows. The vulnerability could allow
remote code execution if a user visited a specially crafted website. An 
attacker would have no way to force users to visit the website. Instead, an 
attacker would have to convince users to take action, typically by getting them
to click a link in an email message or Instant Messenger message that takes 
users to the attacker's website.

This security update is rated Critical for affected versions of the VBScript 
scripting engine on affected Windows clients and Moderate for affected versions 
of the VBScript scripting engine on affected Windows servers.

Affected Software 

VBScript 5.6 (2909213)
VBScript 5.7 (2909212)
VBScript 5.8 (2909210)

Vulnerability Information

VBScript Memory Corruption Vulnerability - CVE-2014-0271

A remote code execution vulnerability exists in the way that the VBScript 
engine handles objects in memory. The vulnerability may corrupt memory in such
a way that an attacker could execute arbitrary code in the context of the 
current user. If the current user is logged on with administrative user rights,
an attacker who successfully exploited this vulnerability could take complete
control of an affected system. An attacker could then install programs; view,
change, or delete data; or create new accounts with full user rights.
