Re: Mutt: failure to check server certificate in SMTP TLS connection

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?
Yes and no. The thing is with gnutls if the certificate is valid for another host - like I had in my test example then gnutls will not show the error and will continue as if there is no error. Obviously if the host has a certificate that is not 'valid' (e.g. self signed) mutt will prompt and ask for you to accept it first . _______________________________________________ Full-Disclosure - We believe in it.
