Nokia firewalls

Hi,
        Well I just unwrapped my shiny new Nokia IP440 integrated
Firewall-1/IDS appliance and thought to give it a once over. It appears
to be a older fBSD kernel + some firewall (checkpoint 4.1) + some IDS
(ISS) + remote admin (SSH/http).

Now these vulnerabilities all require an authenticated user, however,
it's still amazing to me that a device with security as it's primary
function would have so many issues.

A request to it's default http administration site...
http://127.0.0.1/cgi-bin/html_page?(Ax6000)&TEMPLATE=main

will result in "Html_gen exited because of signal: Segmentation fault"
After this, any attempt to connect to the site will return,
"Error while getting page: Couldn't connect to /tmp/xsets: No such file
or directory"

the /bin/xpand will die, dumping core in /var/tmp...
scrooge:/var/tmp# gdb -c xpand.core-11.27.2000-094458

Anyhow, I just thought they may want to clean these things up...
