+	<h1>Problem Description:</h1>
+	<p>With a 'scrub fragment reassemble' rule, a packet containing multiple IPv6
+	fragment headers would be reassembled, and then immediately processed.  That
+	is, a packet with multiple fragment extension headers would not be recognized
+	as the correct ultimate payload. Instead a packet with multiple IPv6 fragment
+	headers would unexpectedly be interpreted as a fragmented packet, rather than
+	as whatever the real payload is.</p>
+	<h1>Impact:</h1>
+	<p>IPv6 fragments may bypass firewall rules written on the assumption all
+	fragments have been reassembled and, as a result, be forwarded or processed
+	by the host.</p>
