Descriptions
Dovecot 2.0.x before 2.0.16, when ssl or starttls is enabled and hostname is used to define the proxy destination, does not verify that the server hostname matches a domain name in the subject's Common Name (CN) of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via a valid certificate for a different hostname.
Dovecot v2.0.x antes de v2.0.16, cuando ssl o starttls está disponible y hostname se usa para definir la destinación del proxy, que no verifica que el servidor hostname busca el nombre del dominio en el sujeto del Common Name (CN) del certificado X.509, que permite ataques man-in-the middle para burlar los servidores SSL a través de un certificado para un hostname diferente.
