(*): 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

Thanks to fellow handlers Johannes, Scott, and Guy!

I disagree with your assessment of the .net patch. It should be "uninstall .net 4 unless you really need it".

Unless a vendor application needs it, there's no reason to be running .net and thus no reason to patch it.

By all means, uninstall if not needed, but our ratings assume that it is installed.

Interesting... MSRT goes after ZeuS/Zbot this month. About time, ya' think?

Side note on MS10-073 per MSSRD Blog http://blogs.technet.com/b/srd/archive/2010/10/12/assessing-the-risk-of-the-october-security-updates.aspx it was one of the exploits used in Stuxnet.

MS10-72,73, and 74 indicate they relate to one or more publically disclosed vulnerabilities. You mention it on 71 and 84, so I figured you'd want to be thorough for the rest.

Is there a, non-toll free, equivalent of 1-866-PCSAFETY for those of us that don't live in the USA?

Just ready MS10-077 carefully. This server patch allows code to be executed on a client. Is there a corresponding client patch?

I run Microsoft Security Essentials on a couple of home machines. Looks like they also released a "client update package" for that product.

anyone else have windows 7 computers explode this morning? I had 3 win7 computers BSOD this morning. I have not determined for certain that it is windows update...but further investigation shows the 3 32-bit win7 machines no longer functioning, but 64-bit win7 still fine.
