Red Hat Linux is a freely available, Open Source clone of the Unix Operating System. It is distributed and maintained by Red Hat Incorporated. A problem with the firewall infrastructure included with the Operating System could make it possible for a administrator to unknowingly expose a system to unnecessary risk. The -c option creates a save-file that is not readable by iptables. When iptables attempts to reload the file at system reboot, it will fail. This makes it possible for an uninformed administrator to leave a system unprotected, and potentially allow access to restricted resources by remote users.
