Re: [FW1] Routing functionality



The vulnerability is that it's a service that doesn't need to be there,
and installing services that don't need to be there in order to work
around problems that exist elsewhere (e.g., internal addressing is
such a mess that the firewall can't get by with a few static routes) is a
bad idea. So you spend some time securing the service -- wouldn't that
time be better spent in fixing the internal address space?

As you said, there are no absolutes in security, and you can't be sure
that your security measures will be effective. There was an interesting
discussion on bugtraq a few months ago about how to break chroot jails in
the context of WU's imapd.
