(*): 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.

Comments
Thank you for the succinct Patch Tuesday updates. I have two comments:
1. It may be important to point out that exploitation on CVE-2013-3660 under MS13-053 was focused on elevation of privilege and not remote code execution. This may impact the severity rating.
2. for MS13-057 and MS13-058, the CVEs referenced in the SANS write-up above are transposed. The correct CVEs are: CVE-2013-3127 for MS13-057 and CVE-2013-3154 for MS13-058.
Regards,

thanks for noticing the typo's - fixed.
As to MS013-053: we did note the more limited capability of the currently used exploit against CVE-2013-3660. But with that kind of attention it's both quite unwise not to patch this, and moreover people usually underestimate the impact of a privilege escalation vulnerability (see here: https://isc.sans.edu/diary/15863 )
