Microsoft Security Bulletin MS12-010 - Critical
Cumulative Security Update for Internet Explorer (2647516)
Published: Tuesday, February 14, 2012
Version: 1.0
General Information
Executive Summary
This security update resolves four privately reported vulnerabilities in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted web page using Internet Explorer. An attacker who successfully exploited any of these vulnerabilities could gain the same user rights as the logged-on 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 7, Internet Explorer 8, and Internet Explorer 9 on Windows clients and Moderate for Internet Explorer 7, Internet Explorer 8, and Internet Explorer 9 on Windows servers. This security update is also rated Moderate for Internet Explorer 6 on all supported editions of Windows XP. 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 content during copy and paste processes, handles objects in memory, and creates and initializes strings. 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 immediately using update management software, or by checking for updates using the Microsoft Update service.
