Message-ID: <87mwwlz43m.fsf@Black.ICE> (raw)
Hi list!
open-gnutls-stream wrapper doesn't pass :verify-hostname-error t
:verify-error t to gnutls-negotiate. So MitM is possible when you use
gnus and other packages.
Even with :verify-hostname-error t :verify-error t gnutls-negotiate
doesn't produce error with selfsigned CA certificate, when :type
'gnutls-x509pki passed.
I use next in my .gnus:
(defun open-gnutls-stream (name buffer host service)
(gnutls-negotiate :process (open-network-stream name buffer host service)
:hostname host
:verify-hostname-error t :verify-error t))
Works for me.
