"An updated jakarta-commons-httpclient package for JBoss Enterprise
Application Platform 5.2.0 which fixes one security issue is now
available for Red Hat Enterprise Linux 4, 5, and 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

The Jakarta Commons HttpClient component can be used to build
HTTP-aware client applications (such as web browsers and web service
clients).

The Jakarta Commons HttpClient component did not verify that the
server hostname matched the domain name in the subject's Common Name
(CN) 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. (CVE-2012-5783)

Warning: Before applying this update, back up your existing JBoss
Enterprise Application Platform installation (including all
applications and configuration files).

All users of JBoss Enterprise Application Platform 5.2.0 on Red Hat
Enterprise Linux 4, 5, and 6 are advised to upgrade to this updated
package. The JBoss server process must be restarted for the update to
take effect."
