When the xz backdoor was discovered, I quickly uninstalled my Arch based setup with an infected version of the software and switched to a distro that shipped an older version (5.5 or 5.4 or something). I found an article which said that in 5.6.1-3 the backdoor was "fixed" by just not letting the malware part communicating with the vulnerable ssh related stuff and the actual malware is still there? (I didn't understand 80% of the technical terms and abbreviations in it ok?) Like it still sounds kinda dangerous to me, especially since many experts say that we don't know the other ways this malware can use (except for the ssh supply chain) yet. Is it true? Should I stick with the new distro for now or can I absolutely safely switch back and finally say that I use Arch btw again?
P. S. I do know that nothing is completely safe. Here I'm asking just about xz and libxzlk or whatever the name of that library is
EDIT: 69 upvotes. Nice
Arch wasn't affected at all, cause the backdoor trigger was only on deb and rpm distros.
However it still a good practice to update your system and leave this version behind. Anyway, Arch already updated and is no longer distributing the backdoor version, therefore 5.6.1-3 is safe
You can use Arch btw again. Actually, you never had to leave it at first
I know that Arch wasn't affected but it's only true for the known ssh backdoor. Afaik that thing can contain 100+ more "viruses" in it that we don't yet know about. And btw I was using a distro that was quite a bit different to Arch (no, not Manjaro) so idk if it was any safer than Debian sid
Well, until someone find a new backdoor, I call it safe again
I'll not lose my mental health to a potentially and unknown shady backdoor that could be installed or not in a lib
Well, I have a polar opposite opinion about that lol. I guess I should stick with the old version
So you need to downgrade to even earlier version. Best of all, use a fork created by Joey Hess.
Does that require compiling Arch from source to avoid compatibility issues?
I don't know for sure, it depends on changes in the liblzma API. If there were any changes (backward compatible or not, usually nobody cares about forward compatibility), yes, recompiling is required.
Then it's not for me. I can't even write a Python script lol
Well, I guess u have your answer, tho
The important thing here is to feel good with your decision
You shouldn't use a computer at all then, your CPU contains Intel and Amd undisclosed backdoor ;)
I know about that
You don't, I'm not talking about Intel ME.
That's the only thing, us the public know about.
This is the reason I keep an OpenBSD system around. Maybe it's a false sense of security, but I feel that they are pickier about the base system at least.
I have a question. Does BSD support any universal package formats?
Afaik, no. Worth mentioning is that the fundamental design of the major BSDs is to clearly separate the core OS from third party applications. But as far as just being able to use Flathub or similar, I don't think so. If any BSD has experimented in that direction my bet would be FreeBSD.
I can't use it then. I need some apps that are definitely not available natively on BSD. Thank you for the information though
No worries :) Just out of curiosity, which software?
Unfortunately telling about the software will greatly simplify my identification so I can't do it
