The September 2014 Security Updates

Today, as a part of our regular Update Tuesday process, we released four security bulletins – one rated Critical and three rated Important in severity – to address 42 Common Vulnerabilities & Exposures (CVEs) in Microsoft Windows, Internet Explorer, .NET Framework, and Lync Server. We encourage you to apply all of these updates, but for those who need to prioritize, we recommend focusing on the Critical update first.

Below is a graphical overview of this release and a brief video summarizing the updates released today:

The top deployment priority for our customers this month is the update for Internet Explorer, which addresses 37 CVEs. In case you missed it, the August update for Internet Explorer also included new functionality to block out-of-date ActiveX controls. This functionality will be bloenabled with today’s update. You can see what these notifications will look like by reviewing this TechNet article. Administrative Templates are also available for those who wish to manage these settings through Group Policy.

In addition to this month’s security bulletins, we have revised three Security Advisories. Security Advisory 2871997 – Update to Improve Credentials Protection and Management was revised to announce an update for supported editions of Windows 7 and Windows Server 2008 R2. The update adds additional protection for users’ credentials when logging into a Windows 7 or Windows Sever 2008 R2 system by ensuring that credentials are cleaned up immediately instead of waiting until a Kerberos TGT (Ticket Granting Ticket) has been obtained. Security Advisory 2905247 – Insecure ASP.Net Site Configuration Could Allow Remote Code Execution was revised to offer the update via Microsoft Update, in addition to the Download-Center-only option, which was provided when this advisory was originally released. If you have already installed this update, you do not need to take any action. Finally, we also revised Security Advisory 2755801: Update for Vulnerabilities in Adobe Flash Player in Internet Explorer.

For more information about this month’s security updates, including the detailed view of the Exploit Index broken down by each CVE, visit the Microsoft Bulletin Summary Web page. If you are not familiar with how we calculate the Exploitability Index (XI), a full description is found here.

Jonathan Ness and I will host the monthly bulletin webcast, scheduled for Wednesday, September 10, 2014, at 11 a.m. PDT.
