Microsoft Security Bulletin MS14-041 - Important
Vulnerability in DirectShow Could Allow Elevation of Privilege (2975681)

Published: July 8, 2014

Version: 1.0

General Information Executive Summary

This security update resolves a privately reported vulnerability in Microsoft
Windows. The vulnerability could allow elevation of privilege if an attacker 
first exploits another vulnerability in a low integrity process and then uses
this vulnerability to execute specially crafted code in the context of the 
logged on user. By default, the modern, immersive browsing experience on 
Windows 8 and Windows 8.1 runs with Enhanced Protected Mode (EPM). For 
example, customers using the touch-friendly Internet Explorer 11 browser on 
modern Windows tablets are using Enhanced Protected Mode by default. Enhanced
Protected Mode uses advanced security protections that can help mitigate 
against exploitation of this vulnerability on 64-bit systems.

This security update is rated Important for all supported editions of Windows
Vista, Windows Server 2008 (excluding Itanium), Windows 7, Windows Server 2008
R2 (excluding Itanium), Windows 8, Windows 8.1, Windows Server 2012, and 
Windows Server 2012 R2.
