wierd: udp port 0 traffic

[Gianni Tedesco <gianni () ecsc co uk>]

Looking through my IDS logs this morning, found a very wierd little
probe a couple of weeks ago. Anyone seen anything like this before?

$ firecat ./db --format ascii --query "sid=525"
  packet: 2003-01-18 15:48:31.267261 len=126 caplen=126
   alert: [sig.udp] BAD TRAFFIC udp port 0 traffic (sid=525.4 prio=3)
