    CVE-2019-1182: https://portal.msrc.microsoft.com/en-US/security-guidance/ad...

    Slightly more technical information from Wired: https://www.wired.com/story/dejablue-windows-bugs-worm-rdp/

    TL;DR: Remote Code Execution via RDP on all windows versions, including 7 and 10.

    Wired Quote:

    > "Microsoft today warned Windows users of seven new vulnerabilities in Windows that, like BlueKeep, can be exploited via RDP, a tool that lets administrators connect to other computers in a network. Of those seven bugs, Microsoft's advisory emphasized that two are particularly serious; like BlueKeep, they could be used to code an automated worm that jumps from machine to machine, potentially infecting millions of computers."

    > "Unlike BlueKeep, however, the new bugs—half-jokingly named DejaBlue by security researchers tracking it—don't merely affect Windows 7 and earlier, as the earlier RDP vulnerability did. Instead, it affects Windows 7 and beyond, including all recent versions of the operating system."

    Only if you have Remote Desktop Connection (RDS) enabled and exposed to the open internet. Which you shouldn't.

    To quote the CVE:

    > Disable Remote Desktop Services if they are not required.

    #

    > Block TCP port 3389 at the enterprise perimeter firewall

    If you're using a VPN or RD Gateway which have been best practice for tens of years, you're already insulated. I'd still patch but outside of business hours.

    I had a feeling something like that was lurking which is why the roll-up was visible but not distributed yet by Windows Update.

    They were testing it for corporate users...

    Anyone know if the latest insider ring builds are affected, or what the minimum build number is to have the fix? I'm currently on build 18956 at home...
