Microsoft quietly yanks botched October patch KB 3000061

Microsoft appears to have pulled last month's MS 14-058/KB 3000061 kernel mode driver patch without warning or explanation

It looks like Microsoft has yanked yet another botched patch without telling anybody. Multiple reports on the AskWoody website prompted me to check all of my unpatched Windows 8 and 8.1 machines, and as best I can tell, KB 3000061 is no longer being offered through Windows Update.

KB 3000061, you may recall, is the October Black Tuesday patch designed to fix a zero-day security hole in win32k.sys that was being actively exploited, in limited situations. Metasploit has details.

KB 300061 also includes nonsecurity updates, detailed in the KB article.

Problems arose when the KB 3000061 installer failed, triggering a rollback. The message boards lit up with complaints. Three days later, poster CountryKING on TechNet came up with a fix, and lord_vader refined the method. It took Microsoft two weeks to confirm the fix, which involves deleting a Registry key.

To this day, there's no official acknowledgment of the problem or its solution in the KB article that's supposed to list known problems.

On Nov. 10, Microsoft engineer joscon posted a TechNet article about the problem and its solution. Two days later, it looks like KB 3000061 has been pulled completely.

Have you seen KB 3000061 lately? Know what happened to it? Enlighten us in the comments section, please.
