Community rules (click to expand)

1. Follow the site-wide rules

Instance-wide TOS: https://legal.lemmy.world/tos/
Lemmy code of conduct: https://join-lemmy.org/docs/code_of_conduct.html

2. Be civil

Understand the difference between a joke and an insult.

Do not harrass or attack members of the community for any reason.

Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.

Bigotry will not be tolerated.

These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.

3. Post Linux-related content

Including Unix and BSD.

Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.

No porn. Even if you watch it on a Linux machine.

4. No recent reposts

Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.

Please report posts and comments that break these rules!

Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't fork-bomb your computer.

liblzma is the problem. sshd is just the first thing they found that it is attacking. liblzma is used by firefox and many other critical packages.

Arch does not directly link openssh to liblzma, and thus this attack vector is not possible. You can confirm this by issuing the following command:

ldd "$(command -v sshd)"

Yes, this sshd attack vector isn't possible. However, they haven't decomposed the exploit and we don't know the extent of the attack. The reporter of the issue just scratched the surface. If you are using Arch, you should run pacman right now to downgrade.
