Description

Red Hat JBoss Enterprise Application Platform is a platform for Java
applications, which integrates the JBoss Application Server with JBoss
Hibernate and JBoss Seam.

It was found that the fix for CVE-2012-5783 was incomplete: the code added
to check that the server host name matches the domain name in a subject's
Common Name (CN) field in X.509 certificates was flawed.
A man-in-the-middle attacker could use this flaw to spoof an SSL server
using a specially crafted X.509 certificate. (CVE-2012-6153)

It was discovered that the HttpClient incorrectly extracted host name from
an X.509 certificate subject's Common Name (CN) field. A man-in-the-middle
attacker could use this flaw to spoof an SSL server using a specially
crafted X.509 certificate. (CVE-2014-3577)

The CVE-2012-6153 issue was discovered by Florian Weimer of Red Hat
Product Security.
