(*): 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.

Microsoft have outdone themselves this month. Every single "contra-indications" KB is missing at this time (19:30 GMT)
The color-coded text is confusing. The "key" says that "white on red" is "PATCH NOW" while "black on red" is "Critical" - yet the table is formatted with "white on red" text that says "Critical". If you're going to use four different styles for the four levels, you should probably follow your style decision (Critical texts needs a "color: black" or "color: #000" rather than currently specified "#fff" value.)

Also, the key text for the fourth level starts with "Less Urt practices", which probably needs some editing.

Obviously, there's no need to publicly post this comment.
Agree, the missing KB's are getting annoying.
KB articles are now in place (22:50 GMT)
We've applied the patches to our test environment PC (Windows 7) and afterwards MS Office failed to open users previous documents. When applied to a second system the same results happened. Highly recommend that everyone test heavily before applying to your production environment.
...and it looks like the Silverlight patch broke NetFlix. Good job MS.
Where are 76-79?
Remember the exchange update was delayed from last month ergo the skip in numbers.
Also be aware of issues with KB3004394
Please note that update MS14-075 for Exchange 2010 SP3 has been removed by Microsoft to "address a know issue"
