Microsoft Security Bulletin MS10-058 - Important
Vulnerabilities in TCP/IP Could Allow Elevation of Privilege (978886)

Published: Tuesday, August 10, 2010 | Updated: Tuesday, March 13, 2012

Version: 2.0
General Information
Executive Summary

This security update resolves two privately reported vulnerabilities in Microsoft Windows. The more severe of these vulnerabilities could allow elevation of privilege due to an error in the processing of a specific input buffer. An attacker who is able to log on to the target system could exploit this vulnerability and run arbitrary code with system-level privileges. The attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

This security update is rated Important 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 vulnerabilities by correcting the way in which the TCP/IP stack handles malformed IPv6 packets and data copied from user mode. 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. The majority of 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.
