(*): 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 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.

Quick note: MS has decided to list out the Adobe Flash updates as a separate security release.

Instead of being buried under KB2755801 then getting another KB from there, it's now listed as part of patch Tuesday, this month: MS16-022

I have a question: if someone has a 2008 R2 server that still has IE8 and IE8 is *not* being used for browsing the Internet, is it still critical for security reasons to get that system to IE11? Is it still vulnerable? Any references would be welcome.

MSHTML.DLL (and other parts of IE) are used by quite some Windows components (and 3rd party applications too): the most prominent example is Windows HTML help.
All these components and 3rd party applications can be (ab)used to exploit the unfixed vulnerabilities in MSHTML.DLL and the other parts of IE<11.
So: YES, it's critical!

MS16-016 does not replace MS16-004, must be a copy-paste error from the previous row (MS16-015).

My MS16-016 is a built-in Windows kernel driver while MS16-004 is an Office vulnerability.
