Microsoft Security Bulletin MS13-049 - Important

Vulnerability in Kernel-Mode Driver Could Allow Denial of Service (2845690)

Published:

Version: 1.0

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 sends specially crafted packets to the server. Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter.

This security update is rated Important for all supported editions of Windows 8, Windows Server 2012, and Windows RT, and Moderate for all supported editions of Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the vulnerability by correcting the way that the Windows TCP/IP driver handles specially crafted packets. For more information about the vulnerability, 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 at the earliest opportunity using update management software, or by checking for updates using the Microsoft Update service.
