+	  <p>Failure to properly bounds check a buffer used for processing
+	    DHCP options allows a malicious server (or an entity
+	    masquerading as a server) to cause a buffer overflow (and
+	    resulting crash) in dhclient by sending a response containing a
+	    specially constructed options section.</p>

+	  <p>A malicious client which is allowed to send very large amounts
+	    of traffic (billions of packets) to a DHCP server can eventually
+	    overflow a 32-bit reference counter, potentially causing dhcpd
+	    to crash.</p>
