(*): 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.

(**): The exploitability rating we show is the worst of them all due to the too large number of ratings Microsoft assigns to some of the patches.

Everything I am reading on the Microsoft page says patch MS12-012 is not applicable for any client operating systems. However, you have it identified as critical. Can you please clarify?

Be aware that KB2668562 Silverlight patch MS12-016 has been throwing off 80070643 errors. The update has been identified as having metadata issue by Microsoft and has been pulled out of the consumer channel. Hold off on approving this update in WSUS until it's been revised.
http://technet.microsoft.com/security/bulletin/MS12-016
- Reason for Revision: V1.1 (February 14, 2012): Added an entry
to the update FAQ to announce a detection change for KB2668562
for Microsoft Silverlight 4 when installed on Windows clients
and servers to correct an installation issue. This is a detection
change only. There were no changes to the security update files.
Customers who have already successfully updated their systems
do not need to take any action.

The CVE for MS12-013 is wrong (that's actually the CVE for MS12-014). The proper CVE should be CVE-2012-0150
