so openssh on mus! linux (alpine, openwrt, buildroot, yocto, and a lot of the docker images you've pulled) has had a little problem since 2016. accounts that should never take a password at all (root, your key-only deploy user, Idap users, the default user on alpine's aws and azure images) take any password longer than 256 characters. yes, any password. yes. i know. yes.

So many embedded systems based on Buildroot, Yocto etc. too.

Remote management in some industrial control systems, healthcare devices, maybe some vehicles, etc.

Chat is it good if any long password works on root? sshhole.com (absolutely incredible name for this vulnerability, too.)

This is obscure as all get out, but by a strange twist of fate I've been working with Alpine Linux for a couple of months. And I'm planning to do some Yocto or Buildroot hacking soon. So ... passing this on.

Another day, another vulnerability learned.

Seems to affect some #linux distros using musl (alpine, openwrt, buildroot, yocto) and potentially some docker images using them.

(alpine, openwrt, buildroot, yocto) is it not using pam? alpine's openssh-server doesn't by default, or maybe you set UsePAM no are password logins still on? they are by default is there an account with just * as its password? key-only users, ldap users, root on alpine and some other account with a real password? then that * account takes any password between 257 and 1024 characters on alpine's official aws and azure images that's the default alpine user, and it has passwordless doas. so it's root on debian, ubuntu, fedora or anything else with glibc? going through pam? dropbear? openbsd? you're fine

Software-update - Home Assistant OS 18.5
Versie 18.5 van Home Assistant OS is uitgekomen. Home Assistant OS is een minimaal, op Buildroot gebaseerd besturingssysteem dat het mogelijk maakt om op een fysieke of virtuele machine Home Assistant te draaien. In versie 18.5 is de Linux-kernel bijgewerkt naar versie 6.18.59, wat daarmee een beveiligingsprobleem verhelpt. De releasenotes voor deze uitgave zien er als volgt uit: Changes
