IPv6 type 0 route headers can be used to mount a DoS attack against

Incorrect mbuf handling for ICMP6 packets.<br>
Using
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pf&sektion=4">pf(4)</a>
to avoid the problem packets is an effective workaround until the patch
can be installed.<br>
Use "block in inet6" in /etc/pf.conf
