FreeBSD Admins: serious telnetd exploit

If you are running FreeBSD (any version 3.1+ (including 4.3-STABLE)) and you are running telnetd, you are vulnerable to this attack.

My suggestion is to patch your telnetd with the link below and turn off telnet access. This is a serious exploit that will both consume large amounts of your bandwidth (due to the nature of the attack) and give the attacker full root access. Any script kiddie can do this -- the exploit is easy to use.
