CVE-2012-5662

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.

Not vulnerable. This issue did not affect the versions of x3270 as shipped with Red Hat Enterprise Linux 5 and 6 as they did not include support for SSL certificate verification.
