<i>All architectures</i><br>
If IPv6 autoconf is active on an interface and the autoconfprivacy extension is used,
redundant addresses are added whenever an autoconfprivacy address expires.
The autoconfprivacy extension is used by default and can be disabled with ifconfig(8)
as a workaround:
<pre>
# ifconfig em0 -autoconfprivacy
</pre>

nginx can reuse cached SSL sessions in unrelated contexts, allowing virtual
host confusion attacks in some configurations.
This issue was assigned CVE-2014-3616.

This patch disables the SSLv3 protocol by default.

Applications depending on SSLv3 may need to be recompiled with
<pre> SSL_CTX_clear_option(ctx, SSL_OP_NO_SSLv3);</pre>

A PF rule using an IPv4 address
followed by an IPv6 address and then a dynamic address, e.g. "pass
from {192.0.2.1 2001:db8::1} to (pppoe0)", will have an incorrect /32
mask applied to the dynamic address.

httpd was developed very rapidly in the weeks before 5.6 release, and
it has a few flaws. It would be nice to get these flaws fully
remediated before the next release, and that requires the community to
want to use it. Therefore here is a "jumbo" patch that brings in the
most important fixes.
