Red Hat Security Advisory
Synopsis: Important: Red Hat JBoss Enterprise Application Platform 6.3 openssl security update
Advisory ID: RHSA-2015:0012-01
Product: Red Hat JBoss Enterprise Application Platform
Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-0012.html
Issue date: 2015-01-05
An update for the OpenSSL component for Red Hat JBoss Enterprise
Application Platform 6.3 that provides a patch to mitigate the
CVE-2014-3566 issue is now available from the Red Hat Customer Portal.
Red Hat Product Security has rated this update as having Important security
Red Hat JBoss Enterprise Application Platform 6 is a platform for Java
applications based on JBoss Application Server 7.
This update adds support for the TLS Fallback Signaling Cipher Suite Value
(TLS_FALLBACK_SCSV), which can be used to prevent protocol downgrade
attacks against applications which re-connect using a lower SSL/TLS
protocol version when the initial connection indicating the highest
supported protocol version fails.
This can prevent a forceful downgrade of the communication to SSL 3.0.
The SSL 3.0 protocol was found to be vulnerable to the padding oracle
attack when using block cipher suites in cipher block chaining (CBC) mode.
This issue is identified as CVE-2014-3566, and also known under the alias
POODLE. This SSL 3.0 protocol flaw will not be addressed in a future
update; it is recommended that users configure their applications to
require at least TLS protocol version 1.0 for secure communication.
For additional information about this flaw, see the Knowledgebase article
All users of Red Hat JBoss Enterprise Application Platform 6.3 as provided
from the Red Hat Customer Portal are advised to apply this update. The
JBoss server process must be restarted for the update to take effect.
