That sounds like a bug, since null scans can only happen in TCP. However,
it might mean that the src and dest port are both 0 in the packet.

Are you using some kind of report interpreter (ie: ACID) or is this present
in the logs snort directly generates?
Can you give an example alert (censor IPs if you wish)?
