Patch Tuesday Analysis for March 2009
MS09-006 replaces last year’s patch MS08-061 both of which patch vulnerabilities with how Windows processes certain image files (WMF and EMF). This is a workstation patch that should be rolled out after normal testing.
MS09-007 only applies to secure web servers that require certificate based client authentication. Simply running an https:// web site doesn’t make you vulnerable to this exploit – only if you are using client certificates. I wrote an article some time ago on how you can implement soft 2-factor authentication using client certificates - http://www.ultimatewindowssecurity.com/articles_certs.html.
Remember DNS spoofing last year. Well here’s another patch with MS09-008 but this one affects only DNS and WINS servers--not the client. Don’t delay in patching vulnerable
DNS servers especially any on the Internet.

"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.
