Microsoft Security Bulletin MS12-078 - Critical
Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Remote Code
Execution (2783534)
Published Date: December 11, 2012
Version: 1.0
General Information
Executive Summary
This security update resolves one publicly disclosed vulnerability and one
privately reported vulnerability in Microsoft Windows. The more severe of these
vulnerabilities could allow remote code execution if a user opens a specially
crafted document or visits a malicious webpage that embeds TrueType or OpenType
font files. An attacker would have to convince users to visit the website,
typically by getting them to click a link in an email message that takes them
to the attacker's website.
This security update is rated Critical for all supported releases of Microsoft
Windows (except Server Core installations, which are rated Important).
