Some kinds of IPv6 usage would leak kernel memory (in particular, this path

was exercised by the named(8) patch for port randomization). Since INET6 is

enabled by default, this condition affects all systems.

<a href="http://www.openssl.org/news/secadv_20090325.txt">OpenSSL security advisory</a>, but note that the other issue described there "Incorrect Error

<i>All architectures</i><br>

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.
|
|
<br>
|
|
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>
