(*): ISC rating

We use 4 levels:
- PATCH NOW: Typically used where we see immediate danger of exploitation. Typical environments will want to deploy these patches ASAP. Workarounds are typically not accepted by users or are not possible. This rating is often used when typical deployments make it vulnerable and exploits are being used or easy to obtain or make.
- Critical: Anything that needs little to become "interesting" for the dark side. Best approach is to test and deploy ASAP. Workarounds can give more time to test.
- Important: Things where more testing and other measures can help.
- Less Urgent: Typically we expect the impact if left unpatched to be not that big a deal in the short term. Do not forget them however.
The difference between the client and server rating is based on how you use the affected machine. We take into account the typical client and server deployment in the usage of the machine and the common measures people typically have in place already. Measures we presume are simple best practices for servers such as not using outlook, MSIE, word etc. to do traditional office or leisure work.
The rating is not a risk analysis as such. It is a rating of importance of the vulnerability and the perceived or even predicted threat for affected systems. The rating does not account for the number of affected systems there are. It is for an affected system in a typical worst-case role.
Only the organization itself is in a position to do a full risk analysis involving the presence (or lack of) affected systems, the actually implemented measures, the impact on their operation and the value of the assets involved.
All patches released by a vendor are important enough to have a close look if you use the affected systems. There is little incentive for vendors to publicize patches that do not have some form of risk to them

As always, please use the contact form for comments about patches.

Please take note that MS10-091 is primarily listed in it's title as "Remote Code Execution" but is also a Elevation of Privilege to Kernel Mode.

MS010-090 should be raised to critical.
ITs currently being exploited and have been alterted by national certs as critical.

I was thinking the same for MS10-092. TDL4 and maybe others use this vulnerability to infect the system.

MS10-091 should have a link to KB2296199, not KB2416400

There are some reports, that KB2416400 fails to install on some Windows 7 x64 systems with error code 80092004. While the exact reasons for the failing aren't known yet AFAIK, it seems to "caused" by an privious installation of a "Hotfix", most likely KB2422556. A german languaged writeup on this (including some possible workarounds) could be found here: http://patch-info.de/artikel/2010/12/14/1005
