I don't think this really needs to be fixed. I think the security bug is that Ubuntu have configured their system in such a way that it will attempt to automount an HFS filesystem on a USB key. By going through FUSE or some other userspace filesystem, the security risk would be eliminated. Is it time to start moving unmaintained obsolescent filesystems with few remaining users into staging? ... Hey, that sounds like a good topic for next week!
