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