this is such a spin! that bug was two years worth of James Bond-level insertions into a situation that "was caused" by systemd ! if you want to get creative in the rewriting of fact
Which library pulled the vulnerability in is mostly irrelevant.
And that was what happened with systemd.
But no. Newer versions of systemd have issues, and this was what systemd pushed. Just why do you think all these distros had the sane patch? For fun?
Arch would have ended up with it eventually. It wasn't Arch being prescient, Arch wasn't using the same systend version as Debian Unstable, and other distros bleeding edge branches.
