6.2.1 and fix three security issues, several bugs, and add various
enhancements are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

Description

Red Hat JBoss Enterprise Application Platform 6 is a platform for Java
applications based on JBoss Application Server 7.

It was found that the ParserPool and Decrypter classes in the OpenSAML Java
implementation resolved external entities, permitting XML External Entity
(XXE) attacks. A remote attacker could use this flaw to read files
accessible to the user running the application server, and potentially
perform other more advanced XXE attacks. (CVE-2013-6440)

It was discovered that the Apache Santuario XML Security for Java project
allowed Document Type Definitions (DTDs) to be processed when applying
Transforms even when secure validation was enabled. A remote attacker could
use this flaw to exhaust all available memory on the system, causing a
denial of service. (CVE-2013-4517)

In Red Hat JBoss Enterprise Application Platform, when running under a
security manager, it was possible for deployed code to get access to the
Modular Service Container (MSC) service registry without any permission
checks. This could allow malicious deployments to modify the internal state
of the server in various ways. (CVE-2014-0018)

The CVE-2013-6440 was discovered by David Illsley, Ron Gutierrez of Gotham
Digital Science, and David Jorm of the Red Hat Security Response Team, and
the CVE-2014-0018 issue was discovered by Stuart Douglas of Red Hat.

This release serves as a replacement for JBoss Enterprise Application
Platform 6.2.0, and includes bug fixes and enhancements. Documentation for
these changes will be available shortly from the JBoss Enterprise
Application Platform 6.2.1 Release Notes, linked to in the References.

All users of Red Hat JBoss Enterprise Application Platform 6.2.0 on Red Hat
Enterprise Linux 5 are advised to upgrade to these updated packages.
The JBoss server process must be restarted for the update to take effect.
