"fail2ban used predictable /tmp files which a local user can allocate
before fail2ban does. All tmp files have been moved to
/var/lib/fail2ban. This also helps with selinux policies.

Another security related fix is that fail2ban defaulted to gamin which
conflicts with selinux, so users had to typically choose between
fail2ban and selinux. fail2ban now defaults to inotify (thanks to
Jonathan Underwood).

There are also some minor bugs fixed :

  - tmpfiles.d support for tmpfs /var/run

    - example mail domains changed to normalized
      example.com.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
