The rlogin command of multiple Unix vendor contains a flaw that may allow a remote attacker to bypass authentication settings. The issue is triggered when using the '-froot' parameter, which allows a remote attacker to gain root access on a system without being prompted for a password resulting in a loss of integrity.

This was reported on a very limited Linux Kernel 0.9x distribution and actively exploited at the time. However, no one seems to have documented the exact version or release (Slackware maybe?).
