Red Hat Security Advisory 2013-0679-01 - The Jakarta Commons HttpClient component can be used to build HTTP-aware client applications. The Jakarta Commons HttpClient component did not verify that the server hostname matched the domain name in the subject's Common Name or subjectAltName field in X.509 certificates. This could allow a man-in-the-middle attacker to spoof an SSL server if they had a certificate that was valid for any domain name. Warning: Before applying this update, back up your existing JBoss Enterprise Application Platform installation .
