Thought you were done after Tuesday's 115-fix day? Not yet: Microsoft emits crisis SMBv3 worm-cure patch

Designated CVE-2020-0796, the bug can be exploited by an unauthenticated attacker to execute malicious code, at administrator level, on an un-patched system simply by sending the targeted system specially crafted compressed data packets. A hacker thus just needs to reach a vulnerable machine on the internet or network to fully compromise it.

[...]"While we have not observed an attack exploiting this vulnerability, we recommend that you apply this update to your affected devices with priority," Microsoft says of the update.

The SMB bug fix was a late addition to Microsoft's March edition of Patch Tuesday – after the security hole was accidentally disclosed by the Cisco Talos research team in a blog post recapping this month's updates: Cisco thought Microsoft had fixed the bug this week as part of March's Patch Tuesday, and alerted the world to the bug's presence to get people to install their updates. In reality, Microsoft hoped to patch the hole later this year, no patch was available, and now everyone knew there was a hole in the compression part of the SMBv3 code.

The revelation sent Microsoft scrambling to post a fix for the flaw just hours after it had emitted updates for 115 other CVE-listed security vulnerabilities.

Designed to allow shared access to files, printers, and hardware ports, SMBv3 is a network protocol included in desktop and server editions of Windows. The bug was particularly nasty as it did not require user interaction and thus could have been exploited by a worm to spread over an entire network.

"Worm". How many here have ever experienced an internet worm? I remember the havoc caused by the original Morris worm when it was released way back on Wednesday, November 2, 1988. We were off the net for at least a full day as our admins tried to figure out what was going on. And even when we got back on-line, things took several days to get back to anything approaching normal.

Not only has the internet grown tremendously over the past 30+ years, the world is now so much more dependent on it.

    MS Office (and Outlook in particular) is the fuck that is going on...

    Every %^&% corporate drone/secretary/pc-specialist-wannabe thinks his/her life (and the world in general) will stop if they cannot use MS Office/Outlook any more.

    So, in some sort of way the shift to Office365 (you know, basically Office on somebody else's machine) might actually be a blessing in disguise once the browser that you use to access Office365 actually can run on a decent-secure-ish OS.

    Then, the only windows computer you'd need to worry about is the server . . .

      Like I wrote: somebody else's machine...
      Therefore: Not my problem, that's what SLA's are for.

      All the above in an ideal world obviously, but not holding my breath for it. :-)

      Since any SLA will be more like "You pay us money, and you still get no warranty whatsoever" (Basically the way Office is working now anyway).
