Special Note: MS15-127 looks particularly "nasty". A remote code execution vulnerability in Microsoft's DNS server. Microsoft rates the exploitability as "2", but doesn't provide much details as to the nature of the vulnerability other than the fact that it can be triggered by remote DNS requests, which is bad news in particular if you are using a Microsoft DNS server exposed to the public internet. In this case, I would certainly expedite this patch. This is the vulnerability to look out for this time around.

(*): 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 a\ re 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 tim\ e to test.
    • Important: Things where more testing and other measures can help.
    • Less Urt 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 threatatches.
