Microsoft Security Bulletin MS10-035 - Critical
Cumulative Security Update for Internet Explorer (982381)

Published: Tuesday, June 08, 2010 | Updated: Tuesday, September 13, 2011

Version: 2.0
General Information
Executive Summary

This security update resolves five privately reported vulnerabilities and one publicly disclosed vulnerability in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted Web page using Internet Explorer. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

This security update is rated Critical for Internet Explorer 6 Service Pack 1 on Microsoft Windows 2000 Service Pack 4; Critical for Internet Explorer 6, Internet Explorer 7, and Internet Explorer 8 on Windows clients; and Moderate for Internet Explorer 6, Internet Explorer 7, and Internet Explorer 8 on Windows servers. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses these vulnerabilities by modifying the way that Internet Explorer handles objects in memory, HTML sanitization, and cached content. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection under the next section, Vulnerability Information.

This security update also addresses the vulnerability first described in Microsoft Security Advisory 980088.

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 immediately using update management software, or by checking for updates using the Microsoft Update service.
