+	  <p>It is possible to crash (SIGSEGV) a NSD child server process
+	    by sending it a non-standard DNS packet from any host on the
+	    internet.  A crashed child process will automatically be restarted
+	    by the parent process, but an attacker may keep the NSD server
+	    occupied restarting child processes by sending it a stream of
+	    such packets effectively preventing the NSD server to serve.</p>
