91: When pf attempts to perform translation on a specially crafted IP datagram,
92: a null pointer dereference will occur, resulting in a kernel panic.
93: In certain configurations this may be triggered by a remote attacker.
1.5 ! sthen 94: <br>
1.4 sthen 95: Restricting translation rules to protocols that are specific to the IP version
96: in use, is an effective workaround until the patch can be installed. As an
97: example, for IPv4 nat/binat/rdr rules you can use:
98: <pre>
99: nat/rdr ... inet proto { tcp udp icmp } ...
100: </pre>
101: Or for IPv6 nat/binat/rdr rules you can use:
102: <pre>
103: nat/rdr ... inet6 proto { tcp udp icmp6 } ...
104: </pre>
