NVD Description
Note: Versions mentioned in the description apply only to the upstream ibm-3270 package and not the ibm-3270 package as distributed by Ubuntu.
x3270 before 3.3.12ga12 does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.
