=====================================================================

1. Summary:

An update for the openssl component for Red Hat JBoss Web Server 2.1.0 that
fixes multiple security issues is now available from the Red Hat Customer
Portal.

Red Hat Product Security 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.

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.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL),
Transport Layer Security (TLS), and Datagram Transport Layer Security
(DTLS) protocols, as well as a full-strength, general purpose cryptography
library.

It was discovered that the OBJ_obj2txt() function could fail to properly
NUL-terminate its output. This could possibly cause an application using
OpenSSL functions to format fields of X.509 certificates to disclose
portions of its memory. (CVE-2014-3508)

Two flaws were discovered in the way OpenSSL handled DTLS packets. A remote
attacker could use these flaws to cause a DTLS server or client using
OpenSSL to crash or use excessive amounts of memory. (CVE-2014-3505,
CVE-2014-3506)

A NULL pointer dereference flaw was found in the way OpenSSL performed a
handshake when using the anonymous Diffie-Hellman (DH) key exchange. A
malicious server could cause a DTLS client using OpenSSL to crash if that
client had anonymous DH cipher suites enabled. (CVE-2014-3510)

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).
