A vulnerability in telnetd code common to FreeBSD and DragonFly was just discovered; it’s been fixed in DragonFly using code from NetBSD in 1995, strangely enough. (via #dragonflybsd on EFNet)
A running description of activity related to DragonFly BSD.
Luckily OpenBSD removed telnet from the system, on account of the total suckage of the protocol.
