NVD Description

Note: Versions mentioned in the description apply only to the upstream openshift-clients package and not the openshift-clients package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

org.apache.http.conn.ssl.AbstractVerifier in Apache HttpComponents HttpClient before 4.3.5 and HttpAsyncClient before 4.0.2 does not properly 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 a "CN=" string in a field in the distinguished name (DN) of a certificate, as demonstrated by the "foo,CN=www.apache.org&#34; string in the O field.
