Package: firehol
Version: 1.231-7
Severity: normal

Firehol is getting started at boot time through init script
/etc/init.d/firehol. While the iptables rules themselves getting loaded,
the policies of the iptables chain's INPUT, OUTPUT, FORWARD, ... remain
in status ACCEPT. After reinvoking

/etc/init.d/firehol restart

the policies changed to DROP - as they should. I can reproduce this
behaviour on several firewalls, where I'm using firehol.

I have not figured out yet, what could cause this condition. Maybe it
could be SELinux, since I only can find here evidences of iptables
settings in /etc/selinux/refpolicy-targeted/contexts/netfilter_contexts.
But the kernel says:

SELinux:  Disabled at boot.

so I'm not sure, if SELinux is still getting invoked and where.

Luckily, firehol uses some finally DROP rules in the ruleset so this is
not that insecure then it looks like. But without them, the firehol may
stay completely open in this case. Anyway it looks like if two systems
are trying to change firewall rules at the same time.

Regards,
Andreas
