(*): 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

UPDATE:

We have been getting reports of people having issues applying MS11-003 (see comments).  No doubt you are testing this in a test environment first anyway, but for this patch you may wish to double check.  Errors of invalid hash and error code 0x80246002.  

If you do have issues with your patches make sure you let Microsoft know via your support channel.

Looks like the first entry should reference MS11-003 instead of MS10-003.
As always, thanks for this useful list.

http://www.microsoft.com/technet/security/Bulletin/MS11-005.mspx regarding "important" for clients, that's patching an active directory domain controller. If a domain controller is a workstation, honey we need to talk. You have bigger problems you need to fix first.

Anyone else notice some installation failures for some of these that install fine once a reboot is performed? MS11-003, MS11-011?

The IE one, MS11-003, will not install on three of three XP SP3 laptops regardless of how many reboots we do. The error code is that the hash is wrong.

Having same problem with MS11-003. Several install attempts on two XP SP3 laptops have resulted in install failures and an error code of 0x80246002.

@JJ & Charles
I bet, you know about http://support.microsoft.com/kb/958056 and have tried the method (cleaning %windir%\SoftwareDistribution\Download) already with no success.
If true, do you have denied access for Everyone to the shimgvw.dll manually (via cacls) or via Fix It 50590 mentioned once in MS Advisory (KB)2490606? If true, you'll have to remove this restriction manually (cacls %WINDIR%\SYSTEM32\shimgvw.dll /E /R everyone) or via Fix It 50593 (in case you've downloaded it earlier).

Ooops, Fix It 50593 can now be found via MSKB article KB2483185 (http://go.microsoft.com/?linkid=9757859).

i too had problems with kb2482017 (MS11-003) on one of two XP Pro SP3 boxes. failed twice using microsoft update website when choosing "custom". third time i chose "express" and it succeeded. why? i don't know, but it succeeded the third time using "express" button rather than "custom" button.

For those having (had) problems with installing MS11-003 (seems to be an Windows XP issue, no other Windows version mentionend until now): It may depend on the IE version you've installed too (IE6, IE7 or IE8).

Yep, I had problems with two machines with MS11-003 using Windows XP SP3 and IE8. However, updating IE8 with Vista and Windows 7 yields no issues. Also, manually downloading the XP SP3 patch and installing it works fine.
