Right, running a machine on public net you have to worry about each
vulnerability which occurs to be a good administrator.

Delivery of not updated original distributions is unfortunately some
kind of common. About your worry missing a firewall set up, I don't
think a firewall makes sense on a dedicated server. What do you want to
prevent with it? Of course, I can imagine specific setups where specific
iptables rules make sense, but a default setup does not need a
firewalling. Either you want to offer services like i.e. webhosting with
Apache and want to be able to administer the server through SSH, or you
won't. So run only the services (daemons) you need and stop the others.
No need to block any port then.

Yes, it is a current cat & mice game. Actually take care the you did not
set register_globals to on in /etc/php.ini. It is off by default and
should stay so.
