=====================================================================

1. Summary:

An updated jakarta-commons-httpclient package for JBoss Enterprise Web
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.

2. Relevant releases/architectures:

JBoss Enterprise Web Platform 5 for RHEL 4 AS - noarch
JBoss Enterprise Web Platform 5 for RHEL 4 ES - noarch
JBoss Enterprise Web Platform 5 for RHEL 5 Server - noarch

3. Description:

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 Web Platform installation (including all applications and
configuration files).

All users of JBoss Enterprise Web 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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
