+When pf attempts to perform translation on a specially crafted IP datagram,
+a null pointer dereference will occur, resulting in a kernel panic.
+In certain configurations this may be triggered by a remote attacker.
+<p>
+Restricting translation rules to protocols that are specific to the IP version
+in use, is an effective workaround until the patch can be installed. As an
+example, for IPv4 nat/binat/rdr rules you can use:
+<pre>
+    nat/rdr ... inet proto { tcp udp icmp } ...
+</pre>
+Or for IPv6 nat/binat/rdr rules you can use:
+<pre>
+    nat/rdr ... inet6 proto { tcp udp icmp6 } ...
+</pre>
