Description Vincent Danen 2011-07-04 22:40:24 UTC

A Debian bug report [1] noted that fail2ban would write temporary files insecurely.  This could allow a local attacker to conduct a symlink attack and overwrite or append to files with root privileges.

Fedora has this fixed already via fail2ban-0.8.4-notmp.patch (0.8.4-27), however EPEL is still vulnerable to this flaw.
