From the man page syslogd(8):
Code:
     -u      Select the historical ``insecure'' mode, in which syslogd will
             accept input from the UDP port.  Some software wants this, but
             you can be subjected to a variety of attacks over the network,
             including attackers remotely filling logs.
And:
Code:
     syslogd opens an Internet domain socket as specified in /etc/services.
     Normally syslogd will only use this socket to send messages outwards, but
     in ``insecure'' mode it will also read messages from this socket....
