@ -4,6 +4,12 @@ vNEXT:
Transparant proxy support for FreeBSD.
(Ruben van Staveren)
Using -F with no argument will try
/etc/sslh/sslh.cfg and then /etc/sslh.cfg as
configuration files. (argument to -F can no longer
be separated from the option by a space, e.g. must
be -Ffoo.cfg)
Call setgroups() before setgid() (fixes potential
privilege escalation).
(Lars Vogdt)
