Nasa are currently working to fix a computer error aboard Voyager 1. The probe's computer system runs at around 8000 instructions per second and has about 68kB of memory. Due to the interplanetary distances involved, even at light speed it takes 45 hours to send a signal and get a response. When asked about the unique challenges this poses, an engineer said "that's actually about average for a modern CI system".

boost this if you're a girl on the fediverse to scare him lmao
I think at a baseline, we shouldn't be building critical official packages for distribution from release tarballs. A huge part of this was the tarball didn't match the repo and since we're talking a compression library, compressed archives shipped for "testing" concealed the payload.
Official builds should pull source and build/test scripts generate testing data in an auditable way rather than just trusting a tarball containing blobs.
"Isn't that a bit alarmist?" No!
xz is a base-system package in literally every distro I know of. It's everywhere.
Compromised releases have been out for five weeks and we didn't notice. We only noticed because someone caught openssh taking 10x as long to do DH exchanges and auth. If the attacker had been sneakier we wouldn't have noticed at all.
The compromised xz was in Fedora's testing versions and they didn't notice. You had the compromised version in Arch for a month (and arguably still do, but a combination of build method and source acquisition method likely renders it safe).
If some random guy didn't go "Why is openssh so slow?" and dig really deep into that, it would have hit stable/live distros and then what? We don't know.
Red Hat released an urgent security alert for Fedora 41 and Rawhide users:
> PLEASE IMMEDIATELY STOP USAGE OF ANY FEDORA 41 OR FEDORA RAWHIDE INSTANCES for work or personal activity.
https://www.redhat.com/en/blog/urgent-security-alert-fedora-41-and-rawhide-users
> Although Fedora 40 beta contained the 5.6 version of xz in an update, the build environment prevents the injection from correctly occurring, and has not been shown to be compromised. Fedora 40 has now reverted to the 5.4.x versions of xz.
