(*): 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.

Given that MS12-083 is for a DirectAccess CA issue and "What systems are primarily at risk from the vulnerability?
Servers are at risk from this vulnerability."
http://blogs.technet.com/b/srd/archive/2012/12/11/ms12-083-addressing-a-missing-certificate-revocation-check-in-ip-https.aspx
As per that blog post, it's the direct access server that can be tricked into allowing a client into the network that should be revoked. The vulnerability is thusly only on the server side, not a client vulnerability.

Yes if you use a Windows 2012 as a workstation you may be offered up this patch but unless you turn that workstation into a DA authentication server it will never be "vulnerable" to attack. I think your grid does a disservice to the risk rating on the "client side" of Server 2008 r2/Server 2012 as I read this.

The chart indicates that MS12-080 has a known exploit but does not indicate which CVE is impacted. I tried searching and can’t find the vulnerability that has the known exploit. Does anyone know which vulnerability it is (Oracle Outside In or RSS Feed)?

Thanks,

Thanks,
I'm having problem with KB2758857. All of the other patches work fine but that one is causing some programs to crash. (MS Money most notably - yes, I know it's been sunsetted)

I get a C++ runtime error with KB2758857 installed. Removing it gets rid of the problem.

Anyone else?
