The discussion to upload it to Debian is interesting on its own https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1067708
Wow, that's a lot of anonymous accounts adding comments there urging for a fast merge! And this "Hans Jansen" guy is apparently running around salsa.debian.org pushing for more updates in other projects as well: https://salsa.debian.org/users/hjansen/activity

My GitHub says exactly who I am!
> openssh does not directly use liblzma. However debian and several other distributions patch openssh to support systemd notification, and libsystemd does depend on lzma. The systemd notification protocol could have been as simple as just writing a newline to a pipe, but instead you have to link to the libsystemd C library, so now security-critical daemons like openssh have additional dependencies like liblzma loaded…

I don't want to read too much into it, but the person (supposedly) submitting the PR seems to work at 1Password since December last year, as per his Linkedin. (And his Linkedin page has a link to the Github profile that made the PR).
Yeah the GitHub account looks really really legitimate. Maybe it was compromised though?
Yikes! Do you have any info on the individual's background or possible motivations?
I would presume it's a state actor. Generally in the blackhat world, attackers have very precise targets. They want to attack this company or this group of individuals. But someone who backdoors such a core piece of open source infrastructure wants to cast a wide net to attack as many as possible. So that fits the profile of a government intelligence agency who is interested in surveilling, well, everything. Or it co…
Most likely this is not the first backdoor, just the first one to be discovered, so it wasn't two years of work until there were results.
But I still agree that he's probably a state actor.
Fascinating. Just yesterday the author added a `SECURITY.md` file to the `xz-java` project. > If you discover a security vulnerability in this project please report it privately. *Do not disclose it as a public issue.* This gives us time to work with you to fix the issue before public exposure, reducing the chance that the exploit will be used before a patch is released. Reading that in a different light, it says giv…
Very annoying - the apparent author of the backdoor was in communication with me over several weeks trying to get xz 5.6.x added to Fedora 40 & 41 because of it's "great new features". We even worked with him to fix the valgrind issue (which it turns out now was caused by the backdoor he had added). We had to race last night to fix the problem after an inadvertent break of the embargo. He has been part of the xz proj…

Is this a crime? Has anyone been prosecuted for adding a backdoor like this?
Has anyone been prosecuted for adding a backdoor Google up Randal Schwartz. Caution: clickhole.
In this case, backdoor code was offered to and accepted by xz maintainers.
