(*): 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.

MS08-070 is a mess. If any 3rd-party VB 6 Apps deployed any of the following OCX files to your machine, you are probably vulnerable!

ComCt232.ocx
MSChrt20.ocx
mscomct2.ocx
MSDatGrd.ocx
MSFlxGrd.ocx
MShflxgd.ocx
msmask32.ocx
MSWINSCK.ocx

In addition, Microsoft isn't providing updates for you, but only to the developer that developed the software. I'm planning on hacking up the MSI they are providing to dike around the VB6 detection logic. Have fun!

Personally, I think Microsoft just violated the rules of responsible disclosure!
