Microsoft Security Bulletin MS13-081 - Critical

Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Remote Code Execution (2870008)

Published: October 08, 2013 | Updated: January 14, 2014

Version: 2.0

General Information

Executive Summary

This security update resolves seven privately reported vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow remote code execution if a user views shared content that embeds OpenType or TrueType font files. An attacker who successfully exploited these vulnerabilities could take complete control of an affected system.

This security update is rated Critical for all supported releases of Microsoft Windows except Windows 8.1, Windows Server 2012 R2, and Windows RT 8.1. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses these vulnerabilities by correcting the way that Windows handles specially crafted OpenType Font files and specially crafted TrueType Font (TTF) files, and by correcting the way that Windows handles objects in memory. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.

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. Customers who have not enabled automatic updating need to check for updates and install this update manually. For information about specific configuration options in automatic updating, see Microsoft Knowledge Base Article 294871.

For administrators and enterprise installations, or end users who want to install this security update manually, Microsoft recommends that customers apply the update immediately using update management software, or by checking for updates using the Microsoft Update service.

A remote code execution vulnerability exists in the way that Windows parses specially crafted OpenType fonts (OTF). An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights.

To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2013-3128.

Mitigating Factors

Mitigation refers to a setting, common configuration, or general best-practice, existing in a default state, that could reduce the severity of exploitation of a vulnerability. The following mitigating factors may be helpful in your situation:

  • 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 these websites. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes users to the attacker's website.
  • By default, the Preview and Details panes are disabled in Windows Explorer in Windows 8. While this prevents malicious files from being viewed in Windows Explorer, it does not prevent a local, authenticated user from running a specially crafted program to exploit this vulnerability.

Workarounds

Workaround refers to a setting or configuration change that does not correct the underlying vulnerability but would help block known attack vectors before you apply the update. Microsoft has tested the following workarounds and states in the discussion whether a workaround reduces functionality:

Disable the Preview Pane and Details Pane in Windows Explorer

Disabling the Preview and Details panes in Windows Explorer prevents OTF fonts from being viewed in Windows Explorer. While this prevents malicious files from being viewed in Windows Explorer, it does not prevent a local, authenticated user from running a specially crafted program to exploit this vulnerability.

To disable these panes in Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2, perform the following steps:

  1. Open Windows Explorer, click Organize, and then click Layout.
  2. Clear both the Details pane and Preview pane menu options.
  3. Close all open instances of Windows Explorer.

Impact of workaround. Windows Explorer will not display OTF fonts.

How to undo the workaround

To re-enable the Windows Explorer Preview pane and Details pane in Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2:

  1. Open Windows Explorer, click Organize, and then click Layout.
  2. Select both the Details pane and Preview pane menu options.
  3. Close all open instances of Windows Explorer for the change to take effect.
