Comment 2 Fabio Valentini 2022-08-12 20:58:30 UTC

Versions of the nix crate that contain the fix for this problem have been available at the time of the Fedora 36 mass rebuild, so any packages available on Fedora 36+ are no longer affected by this problem. I haven't dug into Fedora 35 packages yet, but spot checking packages that *might* be affected, they have all already been rebuilt against a version of nix that no longer has this flaw.
