Common applications that do this are tcpdump, trafshow and ntop. If you've used one of these they will by default try and analyze -all- traffic they can get hold of, instead of just that destined for one of your machines. It is logged because it is a potential security issue. If you have not used any tools like the above, you could have a password sniffer or something like that installed without your knowledge.
