Microsoft Security Bulletin MS14-045 - Important
Vulnerabilities in Kernel-Mode Drivers Could Allow Elevation of Privilege (2984615)
Published: August 12, 2014 | Updated: August 27, 2014
Version: 3.0
General Information
Executive Summary
This security update resolves three privately reported vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow elevation of privilege if an attacker logs on to the system and runs a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit these vulnerabilities.
This security update is rated Important for all supported editions of Microsoft Windows. For more information, see the Affected and Non-Affected Software section.
The security update addresses the vulnerabilities by correcting the way that Windows handles thread-owned objects, by correcting the way in which specially crafted font files are handled in memory by Windows, and by correcting the way in which memory is allocated. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability later in this bulletin.
Recommendation. Most customers have automatic updating enabled and will not need to take any action because this security update will be downloaded and installed automatically. For information about specific configuration options in automatic updating, see Microsoft Knowledge Base Article 294871. For customers who do not have automatic updating enabled, the steps in Turn automatic updating on or off can be used to enable automatic updating.
For administrators and enterprise installations, or end users who want to install this security update manually (including customers who have not enabled automatic updating), Microsoft recommends that customers apply the update at the earliest opportunity using update management software, or by checking for updates using the Microsoft Update service. The updates are also available via the download links in the Affected Software table later in this bulletin.
