It also turns out that I didn't test this issue enough. As I didn't
test with both gnutls and openssl. I only tested with gnutls. Mutt
actually works as I would expect with imaps, smtps and smtp -- with
starttls connection when using openssl. mutt appears to be _broken_
when using gnutls for imaps, smtps and smtp -- with starttls. (on mutt 1.5.20).
Hi,
I've tested this behaviour using both - gnutls and openssl - and it
seems like the only difference is that there is an error printed using
openssl: "Certificate host check failed: certificate owner does not
match hostname imap.myhost.web".
In both cases a user can accept the certificate, but there is no warning
about certificate's hostname mishmash using gnutls, which is a
vulnerability.
I just wanted to sum up the issue, do I understand it correctly?
