I might be missing something, but I don't see any issue here... That dir is world readable, but not writable. Nothing inside it that is sensitive is readable to non priv users. rkhunter uses mktemp for temp files, so they should be fine. I suppose we could change the dir to 700, but I don't see a urgent reason to. Read the documentation: rkhunter may copy temporary files (or parts of) from other system locations there in order to scan/analyze them. So you could have something like /etc/unaccessible-dir/readable-password-file which is copied there, and then the protection from unaccessible-dir no longer applies. The proper way is to use the default for TMPDIR, which is /var/lib/rkhunter/tmp and create that dir u=rwx,go= Cheers, Chris. rkhunter-1.4.2-5.fc21 has been submitted as an update for Fedora 21. https://admin.fedoraproject.org/updates/rkhunter-1.4.2-5.fc21 rkhunter-1.4.2-5.fc20 has been submitted as an update for Fedora 20. https://admin.fedoraproject.org/updates/rkhunter-1.4.2-5.fc20 rkhunter-1.4.2-5.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/rkhunter-1.4.2-5.fc19 rkhunter-1.4.2-5.el7 has been submitted as an update for Fedora EPEL 7. https://admin.fedoraproject.org/updates/rkhunter-1.4.2-5.el7 rkhunter-1.4.2-4.el6 has been submitted as an update for Fedora EPEL 6. https://admin.fedoraproject.org/updates/rkhunter-1.4.2-4.el6 Package rkhunter-1.4.2-5.fc20: * should fix your issue, * was pushed to the Fedora 20 testing repository, * should be available at your local mirror within two days.
