The Red Hat Security Response Team has rated this update as having Moderate

which give detailed severity ratings, are available for each vulnerability

Description

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

Apache CXF is an open source services framework, which is a part of
Red Hat JBoss Enterprise Application Platform.

It was found that the SecurityTokenService (STS), provided as a part of
Apache CXF, could under certain circumstances accept invalid SAML tokens as
valid. A remote attacker could use a specially crafted SAML token to gain
access to an application that uses STS for validation of SAML tokens.
(CVE-2014-0034)

A denial of service flaw was found in the way Apache CXF created error
messages for certain POST requests. A remote attacker could send a
specially crafted request which, when processed by an application using
Apache CXF, could consume an excessive amount of memory on the system,
possibly triggering an Out Of Memory (OOM) error. (CVE-2014-0109)

It was found that when a large invalid SOAP message was processed by Apache
CXF, it could be saved to a temporary file in the /tmp directory. A remote
attacker could send a specially crafted SOAP message that, when processed
by an application using Apache CXF, would use an excessive amount of disk
space, possibly causing a denial of service. (CVE-2014-0110)

It was found that the Java API for RESTful Web Services (JAX-RS)
implementation enabled external entity expansion by default. A remote
attacker could use this flaw to view the contents of arbitrary files
accessible to the application server user. (CVE-2014-3481)

It was discovered that UsernameTokens were sent in plain text by an Apache
CXF client that used a Symmetric EncryptBeforeSigning password policy.
A man-in-the-middle attacker could use this flaw to obtain the user name
and password used by the client application using Apache CXF.
(CVE-2014-0035)

The CVE-2014-3481 issue was discovered by the Red Hat JBoss Enterprise
Application Platform QE team.

This release serves as a replacement for Red Hat JBoss Enterprise
Application Platform 6.2.3, and includes bug fixes and enhancements.
Documentation for these changes will be available shortly from the Red Hat
JBoss Enterprise Application Platform 6.2.4 Release Notes, linked to in
the References.

All users of Red Hat JBoss Enterprise Application Platform 6.2 on Red Hat
Enterprise Linux 6 are advised to upgrade to these updated packages.
The JBoss server process must be restarted for the update to take effect.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied. Also, back up any customized Red
Hat JBoss Enterprise Application Platform 6 configuration files. On update,
the configuration files that have been locally modified will not be
updated. The updated version of such files will be stored as the rpmnew
files. Make sure to locate any such files after the update and merge any
changes manually.
