I received a buffer overflow attack on 12/18/05, destined to tcp port 105. This is the first buffer overflow against that port that I have seen. I don't know what runs on tcp/105, but some places say "Mailbox Name Nameserver". I find this answer believeable.

Port 105 used for "ph" aka CCSO Nameserver. See RFC 2378.
