- update to 2.3.4.1 (boo#1123022)
* CVE-2019-3814: If imap/pop3/managesieve/submission client has
trusted certificate with missing username field
(ssl_cert_username_field), under some configurations Dovecot
mistakenly trusts the username provided via authentication
instead of failing.
* ssl_cert_username_field setting was ignored with external
SMTP AUTH, because none of the MTAs (Postfix, Exim) currently
send the cert_username field. This may have allowed users with
trusted certificate to specify any username in the
authentication. This bug didn't affect Dovecot's Submission
service.
