NVD Description

Note: Versions mentioned in the description apply only to the upstream dovecot-devel package and not the dovecot-devel package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

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.
