You could use the nessus "binlogin_overflow_telnet.nasl" script to verify
if your system is vulnerable. Also a quick way to check for SysV option
capabilities is to type "login", then enter "root testenv1=test" at the
login: prompt. Supply your root passwd, and look for the "testenv1"
environment variable. If it is set, then your copy of /bin/login supports
SysV options, and is probably
