We will update issues on this page for about a week or so as they evolve.
We appreciate updates
US based customers can call Microsoft for free patch related support on 1-866-PCSAFETY
(*): 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

I'm getting Code 80070643, unknown error, when I try to install KB2183461 on a relatively fresh install of Windows 7 Professional 32-bit.

MS010-46 is listed in MS's August rollout, even though it was released last week. You might want to provide current intel on that in your table here, for those that haven't applied it yet, since it is publically disclosed and active.

I was able to install all updates except KB2183461, KB983590 and KB978886 (on Win 7 32bit). KB978886 actually did install but on reboot my network failed with "The TCP/IP Protocol Driver service failed to start due to the following error: The system cannot find the file specified." in the event log. I had to uninstall from the command line to get it to work (Windows Updates in control panel would not show the previously installed updates...)

The other 2 updates would not install at all and gave me the error I reported above, ie. 80070643, unknown error.

At the moment I guess nobody else is seeing this so it must be somewhat rare... but if someone does come across this, the solution was (from CMD): wusa.exe /uninstall /kb:<KB Number> (that is, 978886.

Hi,

I'm wondering why MS10-049 (SChannel) is Important for Clients and Critical for Servers when from everything I can work out it's a Client-Side Vuln.? What am I missing?

Also, there's been exploit code released for MS10-054 as of the 10th:

After patching and rebooting some of the 2003 and 2008 servers here we had a DNS server failure. It would not resolve addresses. Another reboot seemed to fix things.

@david, A server can act as a client too. (although not recommended)

-049 is critical for servers because it finally includes the fix for the TLS/SSL renegotiation issue from last Nov for IIS 6 & 7. It appears that PoC's exist for -051 and -054 as well, we probably won't update the table again, but will do new diary entries if we start seeing this vulnerabilities being exploited in the wild.

so why Important for Clients but Critical for Servers? Especially seeing how it's RCE with SYSTEM privs for clients (from a shady memory)

I have a question regarding last month's MS OFFICE SP1 end of life.

Do I need to assume Office SP1 is also vulnerable (Word vulnerability)?
Microsoft has omitted to state this in its bulletin, probably because they no longer offer patches for SP1.
If someone could clarify this point it would be quite useful.
