Patch Analysis for October 2012

OK, this is an interesting month of patches – and not your usual month of primarily workstation patches. There are some patches that affect workstations though, but they also affect SharePoint and Groove servers – basically any apps that work with documents. So besides Office that includes Groove, Lync, Infopath, etc. There’s also a FAST search server (a component of SharePoint) patch that you might be able to work around. Then there’s a weird Kerberos-based denial-of-service vulnerability. Microsoft indicates it affects the “Kerberos server” which to me says “domain controller” but the patch is for both Windows Server and Windows 7… Finally there is a patch for SQL Server in Report Manager. This is an XSS (cross-site scripting) vulnerability and those are always tricky to get your head around because they can be prevented on the server and web client. Of course you need to prevent it at the server, primarily.
The 2 that you should jump on first are MS12-066 and MS12-067 because their exploit details are public and at least MS12-066 is already being exploited.
Before I take you to the chart for this month’s patches, here’s a quick note about a useful and free tool from Lumension that assesses and prioritizes your vulnerabilities by criticality and delivers actionable information through an intuitive user interface, where users can easily create a variety of PDF-based reports about vulnerabilities for your OS, applications, policies and security configurations. It scans up to 25 nodes which is a good sample size to gauge the security of your systems. The scanner is located here at Lumension.
And check out Lumension Patch and Remediation for multi-vendor, multi-platform patch management that’s a part of a much larger, single-agent, single pane-of-glass endpoint security management solution.

"I liked your high level overview of patches in the table. There are so many sources of patch information which can be very specific or surrounded by other stuff that it’s refreshing to get everything summarised like this. The “Randy’s Recommendation” comment is useful starting point too. Please keep up the good work."

- David A.

"Your Patch Observer is a very good tool in making the decision whether to patch or not to patch. And also to patch asap or to wait a while before patching. Also I do think the use of the table is realy improving the readability of the provided information."
