Fedora has issued an advisory today (June 23): https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/LKUIBK6AL4IANDOSBXD3Y3XK33FGNP5B/ It's not clear what the security issue is (perhaps the gtk #4880 that it mentions), or if it affects Mageia 8.
ghex-44.1-1.mga9 is in Cauldron
