<i>All architectures</i><br>
Inverted logic made PermitRootLogin "prohibit-password" unsafe.
Use "no" (which is the installer default), or apply the following patch.

LibreSSL 2.2.2 incorrectly handles ClientHello messages that do not
include TLS extensions, resulting in such handshakes being aborted.

<i>All architectures</i><br>
Fix multiple reliability and security issues in smtpd:<br>
<ul>
<li>local and remote users could make smtpd crash or stop serving requests.
<li>a buffer overflow in the unprivileged, non-chrooted smtpd (lookup)
process could allow a local user to cause a crash or potentially
execute arbitrary code.
<li>a use-after-free in the unprivileged, non-chrooted smtpd (lookup)
process could allow a remote attacker to cause a crash or potentially
execute arbitrary code.
<li>hardlink and symlink attacks allowed a local user to unset chflags or
leak the first line of an arbitrary file.

A replacement file is available</a> in the 5.8 release directory with the name <b>cd-src.tar.gz</b>; due to size of the file, check local mirrors also.
