Cumulative Security Update for Internet Explorer (2744842)

Published: Friday, September 21, 2012

Version: 1.0
General Information
Executive Summary

This security update resolves one publicly disclosed and four privately reported vulnerabilities in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited any of these vulnerabilities could gain the same user rights as the current 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, Internet Explorer 8, and Internet Explorer 9 on Windows clients and Moderate for Internet Explorer 6, Internet Explorer 7, Internet Explorer 8, and Internet Explorer 9 on Windows servers. Internet Explorer 10 is not affected. 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. 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 2757760.

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

Be sure your Browser settings are set to IE, assuming you want IE as your default Browser.

Updated finally after getting the kids to sleep.It would have done so automatic but being in Shadow Mode full time the updates get trashed on every reboot.A small inconvenience to keep the system safe.

Microsoft Could Have Known About IE Security Flaw In Advance

It has been suggested that Microsoft knew about the recent IE security flaw which hit its Internet Explorer browser last week, almost two months before it came to the attention of the experts.

On 15 September, Microsoft acknowledged that an IE security flaw was being actively targeted for attacks using a previously unknown and unpatched vulnerability, after it was identified by Romang, a security researcher from the Metasploit project.

The vulnerability was present in Internet Explorer 9 and earlier versions. According to Microsoft, it “could allow remote code execution if a user views a specially crafted webpage using Internet Explorer.” An attacker who successfully exploited this vulnerability “could gain the same user rights as the current user.”
