An incredibly technically complex #backdoor in xz (potentially also in libarchive and elsewhere) was just discovered. This backdoor has been quietly implemented over years, with the assistance of a wide array of subtly interconnected accounts:

- https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1067708
- https://github.com/jamespfennell/xz/pull/2
The timeline on this is going to take so long to unravel

I have begun a post explaining this situation in a more detailed writeup. This is updating in realtime, and there is a lot still missing.
@eb I really hope that this causes an industry-wide reckoning with the common practice of letting your entire goddamn product rest on the shoulders of one overworked person having a slow mental health crisis without financially or operationally supporting them whatsoever. I want everyone who has an open source dependency to read this message https://www.mail-archive.com/xz-devel@tukaani.org/msg00567.html
@eb "I never thought a sophisticated APT would backdoor *my* volunteer-maintained infrastructure that I got for free" sobs entire industry who voted for the "volunteer-maintained infrastructure that I get for free with no defense against sophisticated APTs" party
@krans @glyph @eb sure. well, so the reason we personally call the thing we do "free software" is precisely to highlight the point that our own goal in publishing stuff without charge is very much to work towards a world without that problem, by creating something that exists as far outside it as we can manage (not all the way - obviously we have the free time to do that because of our other privileges)
@irenes @glyph @eb I thought it was called "free software" because users are allowed to do whatever they want to with it including modifications, not because it's provided free of charge.
The founders of the Free Software movement were Libertarians, not Socialists (unfortunately).
I guess we were talking at cross purposes — sorry.
@krans @glyph @eb we're very proactive-death-of-the-author about this. the FSF has failed to provide ideological leadership due to RMS's top-down style, but many of the ideals are good ones and it's the job of the current generation to renew the movement if we want our children to be able to enjoy its fruits the way we did
@irenes @glyph @eb I stopped publishing FOSS because there were too many people who took the code, used it to make a tonne of money, and contributed nothing back other than abuse.
Now I get paid really well for doing *almost exactly the same work* in a really supportive proprietary R&D team, with customers who both pay huge license fees and treat us with respect.
