1. Summary:

An update for the JBoss Web Services component in JBoss Enterprise
Application Platform 4.3.0 CP10 which fixes one security issue is now
available from the Red Hat Customer Portal.

The Red Hat Security Response Team has rated this update as having
important 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. Description:

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

An attack technique was found against the W3C XML Encryption Standard when
block ciphers were used in cipher-block chaining (CBC) mode. A remote
attacker could use this flaw to conduct chosen-ciphertext attacks, leading
to the recovery of the entire plain text of a particular cryptogram by
examining the differences between SOAP (Simple Object Access Protocol)
responses sent from JBoss Web Services. (CVE-2011-1096)

Red Hat would like to thank Juraj Somorovsky of Ruhr-University Bochum for
reporting this issue.

Note: Manual action is required to apply this update. The CVE-2011-1096
issue is an attack on the WS-Security standard itself. Using new
Galois/Counter Mode (GCM) based algorithms for WS-Security encryption is
the W3C suggested way of dealing with this issue. To use GCM algorithms in
your application, update the encrypt element of all jboss-ws-security
configuration to specify a GCM algorithm. The following is an example

encrypt type="x509v3" algorithm="aes-128-gcm" alias="wsse"

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 4.3.0 CP10 as provided
from the Red Hat Customer Portal are advised to apply this update.

3. Solution:

The References section of this erratum contains a download link (you must
log in to download the update). Before applying the update, back up your
existing JBoss Enterprise Application Platform installation (including all
applications and configuration files).

The JBoss server process must be restarted for this update to take effect.

4. Bugs fixed (http://bugzilla.redhat.com/):
