Very Bad Word Edition

Top Story

  • Just a five days ago I wrote this:

    It's been a while since we've had a big tech news story. No disasters, no miracles. Things haven't suddenly gotten better - or at least, not much, and they haven't gotten drastically worse.

    Well.

    A Linux exploit has been found that instantly grants root access to local users on most Linux versions released since 2017.  (Tom's Hardware)
    Although it's not a zero-day and the kernel has already gotten a patch, the short disclosure window gave distro makers relatively little time to react.  Affected variants include (but aren't limited to) Ubuntu 24 (version 26 was just released last week), RHEL 10, Suse 16, and Amazon Linux 2023. Even Windows' WSL2 is affected, and all it takes is 732 bytes to do it.
    Fortunately for me, only one server was potentially vulnerable, and that one didn't have the affected module loaded, and I've now disabled it completely.

    But even more sysadmins are having a bad day.


  • Like the ones at Canonical - the company behind the popular Ubuntu Linux release - whose corporate servers are mostly dead right now thanks to a massive ongoing DDOS attack.  (Tom's Hardware)

    If you're already installed Ubuntu you are still able to load updates - like the patch for the so-called CopyFail bug mentioned above - from the numerous mirrors, which don't seem to be affected at all.


  • My own server decided to drop dead, completely unrelated to all the other drama going on in the Linux world.

    Fortunately I set it up years ago to make migrations easy - and to keep backups separate from the system disk.  But it still took a few hours to get it all working smoothly.

    The silverfish lining is that I've wanted to do this for months but it never hit the top of my to do list.  I already had a new server, twice the size of the old one and actually cheaper.  So that's where we are now.
