Just wondering. What happens if you create a symlink to .rhosts and manage to write a "+ +" in memory before coredump (i've not checked if it's possible in this particular situation)? Or maybe symlinking /etc/passwd and causing a DoS condition? This is just an example, but i'm not so sure it's not possible to exploit this behaviour of a setuid program...

Please correct me if i'm plain wrong:)
