Cumulative Security Update for Internet Explorer (2482017)

Published: February 08, 2011

Version: 1.0


General Information

This security update resolves two privately reported vulnerabilities and two publicly disclosed vulnerabilities in Internet Explorer. The vulnerabilities could allow remote code execution if a user views a specially crafted Web page using Internet Explorer or if a user opens a legitimate HTML file that loads a specially crafted library file. An attacker who successfully exploited any of these vulnerabilities could gain the same user rights as the local user. 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, 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 the vulnerabilities by modifying the way that Internet Explorer handles objects in memory, handles Cascading Style Sheets, and loads external libraries. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.


This security update also addresses the vulnerability first described in Microsoft Security Advisory 2488013.


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, seeMicrosoft 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.
