Updated Gnome-lokkit packages fix missing FORWARD ruleset in Red Hat Linux 8.0
Gnome-lokkit is a utility that provides firewalling for the average Linux end user based on responses to a small number of simple questions. Red Hat made modifications to Gnome-lokkit to support firewalls based on iptables instead of ipchains. In Red Hat Linux 8.0, the iptables ruleset created by Gnome-lokkit did not place any rules on the FORWARD chain. This is a security vulnerability if an administrator enables packet forwarding and uses an unmodified ruleset created by the Gnome-lokkit tool. Users are advised to upgrade to these erratum packages which contain a patch to Gnome-lokkit to also apply the INPUT chain ruleset to the FORWARD chain. Red Hat would like to thank Deneb Meketa for bringing this issue to our attention.
