Synopsis:          Important: Red Hat JBoss Web Server 2.1.0 openssl security update
Advisory ID:       RHSA-2014:1920-01
Product:           Red Hat JBoss Web Server
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2014-1920.html
Issue date:        2014-12-01
=====================================================================

1. Summary:

An update for the openssl component for Red Hat JBoss Web Server 2.1.0 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
impact.

2. Description:

Red Hat JBoss Web Server is a fully integrated and certified set of
components for hosting Java web applications. It is comprised of the Apache
HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector
(mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat
Native library.

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
at https://access.redhat.com/articles/1232123

All users of Red Hat JBoss Web Server 2.1.0 as provided from the Red Hat
Customer Portal are advised to apply this update. The Red Hat JBoss Web
Server process must be restarted for the update to take effect.

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 Red Hat JBoss Web Server installation (including all applications
and configuration files).
