Arch has already updated XZ by relying on the source code repository itself instead of the tarballs that did have the manipulations in them.

It's not ideal since we still rely on a potentially *otherwise* compromised piece of code still but it's a quick and effective workaround without massive technical trouble for the issue at hand.

My only exposure to Linux is SteamOS so I might be misunderstanding something, but if not:

How in the world did it get infected in the first place? Do we know?

From what I read it was one of the contributors. Looks like they have been contributing for some time too before trying to scooch in this back door. Long con.

It seems like this contributor had malicious intent the entire time they worked on the project. https://boehs.org/node/everything-i-know-about-the-xz-backdoor

Wow. That is some read.

edit:I keep thinking my jaw can't go any closer to the floor but I keep reading and my jaw keeps dropping.

HOLY COW!

Basically, one of the contributors that had been contributing for quite some time (and was therefore partly trusted), commited a somewhat hidden backdoor. I doubt it had any effect (as it was discovered now before being pushed to any stable distro and the exploit itself didnt work on Arch) bjt we'll have to wait for the effect to be analyzed.
