Patch Tuesday Analysis for January 2008
Only 2 bulletins this month and neither is what I’d call high priority unless you manage a server exposed to the Internet that sends or receives multi-cast traffic. If you have systems connected to hostile networks that are open to IGMP/MLD and Router Discovery Protocol you should load this patch as soon as possible. Of course workstations are typically in this category but I would recommend testing the patch before rolling out to hundreds or thousands of workstations. Your other option – for systems that don’t need to support multicast traffic – is to disable the features with a registry tweak that can be automated through group policy with a custom administrative template.
The other vulnerability is limited to the risk of someone logged on locally who runs a specially crafted program which elevates its privileges. This is mostly a matter for high security workstation environments where end users don’t have admin authority and Terminal Servers where end-users could access and execute a specially crafted program.

"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."

"Your Patch Tuesday 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."
