- 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.

NOTE: These security updates also included an update for Windows 8 Customer Preview. Updates for Windows 8 are available through the operating systems Windows Update. (Thanks Rene! - Mark Baggett)
SAMBA "root" credential remote code execution.
Samba - "a Windows SMB/CIFS fileserver for UNIX" seems to have a serious security vulnerability that samba versions 3.6.3 and all versions prior to it have a vulnerability that allows remote code execution as the "root" user from an anonymous connection.
Yep, time to upgrade SAMBA.

Windows Vista RIP
Microsoft Windows Vista was your full name. Internally you identified yourself as windows 6.0. Most would call you simply Vista. You were never liked all that much. In part this was due to your security inspired nanny attitude. Despite that, you carried a lot of essential and long overdue security improvements. Improvement which allowed e.g. the practical removal of administrator rights without impacting the users of software written under the false presumption that users should have administrative rights.
The market has rejected you and killed you off. Your last copies went over the counter in October 2011 according to your maker. And finally, today that same maker buries you too: Microsoft is stopping support for Windows Vista today.
There is some hope that consumer rights groups will fight such a short lifespan of support and patches (e.g. in Europe there 's a mandatory 2 year warranty requirement for products sold to consumers), but overall and for all practical purposes, you're about to be forgotten by all but a handful who'll send significant donations to your maker.
So you will nonetheless live on for a while -for a maximum of 5 more years- through extended support as well as through your technically very closely related sibling Windows 7 (which identifies itself internally as windows 6.1 in a sort of tribute to you), and which was given a bit better of an education on how to interact with the public by the maker's marketing department.
Still those that have you will now have to decide to bury you in the trashcan or pay for extended support.

- I hope this doesn't offend any of our readers. it's only meant to be a bit sarcastic and to lighten up the rainy day a bit.
