Microsoft Security Bulletin MS14-033 - Important
Vulnerability in Microsoft XML Core Services Could Allow Information Disclosure
(2966061)

Published: June 10, 2014

Version: 1.0

General Information

Executive Summary

This security update resolves a privately reported vulnerability in Microsoft 
Windows. The vulnerability could allow information disclosure if a logged on 
user visits a specially crafted website that is designed to invoke Microsoft 
XML Core Services (MSXML) through Internet Explorer. In all cases, however, an 
attacker would have no way to force users to visit such websites. Instead, an 
attacker would have to convince users to visit a website, typically by getting
them to click a link in an email message or in an Instant Messenger request 
that takes users to the attacker's website.

This security update for Microsoft XML Core Services 3.0 and Microsoft XML 
Core Services 6.0 is rated Important on all supported releases of Microsoft 
Windows clients and Low for all supported releases of Microsoft Windows
servers. 

Affected Software 

Windows Server 2003 Service Pack 2 - Microsoft XML Core Services 3.0 
Windows Vista - Microsoft XML Core Services 3.0 
Windows Server 2008 - Microsoft XML Core Services 3.0 
Windows 7 - Microsoft XML Core Services 3.0 
Windows Server 2008 R2 - Microsoft XML Core Services 3.0 
Windows 8 and Windows 8.1 - Microsoft XML Core Services 3.0 
Windows Server 2012 and Windows Server 2012 R2 - Microsoft XML Core 
Services 3.0 
Windows RT and Windows RT 8.1 - Microsoft XML Core Services 3.0 

MSXML Entity URI Vulnerability - CVE-2014-1816
