Microsoft Security Bulletin MS14-079: KMD (3002885)

Vulnerability in Kernel-Mode Driver Could Allow Denial of Service

Version: 1.0

Published Date: November 11, 2014

General Information

Executive Summary

This security update resolves a privately reported vulnerability in Microsoft
Windows. The vulnerability could allow denial of service if an attacker places
a specially crafted TrueType font on a network share and a user subsequently 
navigates there in Windows Explorer. In a web-based attack scenario, an 
attacker could host a website that contains a webpage that is used to exploit
this vulnerability. In addition, compromised websites and websites that accept
or host user-provided content or advertisements could contain specially 
crafted content that could exploit this vulnerability. In all cases, however,
an attacker would have no way to force users to visit such websites. Instead,
an attacker would have to persuade users to visit a website, typically by 
getting them to click a link in an email message or Instant Messenger message
that takes them to the attacker's website.

This security update is rated Moderate for all supported releases of Microsoft
Windows.
