rlogin -froot
this old flaw has recently gained new popularity. It's a high risk, cause root can be taken remotly, therefor, make sure /bin/login isn't vulnerable to the known bug, rlogin -froot
You need to upgrade your /bin/login or if you want to be sure, you can comment out the rlogin line in your /etc/inetd.conf
