Take a look at the Digium website.  The advisories are there.

IAX2 has one (if I remember correctly it eats up all the channel's resources causing a denial of service).

Leon,
I've heard this before about old Asterisk. Any notes you can point to detailing security issues in 1.4?

from someone who has worked at a service provider doing managed services (routers and firewalls) you want to heed NerdUno (Ward Mundy's) words to never expose Asterisk to the internet, and especially since this is old ASterisk. You want some sort of firewall appliance in front of it.

I personally prefer VPN tunnels coming back in but you can get crafty and do port forwards with unknown ports to like 22 and 80 but there's always that risk of someone catching on. Tunnels are the safest way to get back inside. You only want to expose only the ports specifically necessary to do the job.

This is a bad idea.  Root should *never* be allowed to login to a system

via su, sudo, etc.
meh, it's more of a local policy thing.  I'd prefer it's not enabled by default, but there are some reasons I could see for enabling it.
