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

1. Summary:

Red Hat JBoss SOA Platform 5.3.1 roll up patch 3, which fixes three
security issues and various bugs, is now available from the Red Hat
Customer Portal.

The Red Hat Security Response Team 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 SOA Platform is the next-generation ESB and business process
automation infrastructure. Red Hat JBoss SOA Platform allows IT to leverage
existing (MoM and EAI), modern (SOA and BPM-Rules), and future (EDA and
CEP) integration methodologies to dramatically improve business process
execution speed and quality.

This roll up patch serves as a cumulative upgrade for Red Hat JBoss SOA
Platform 5.3.1. It includes various bug fixes. The following security
issues are also fixed with this release:

The Jakarta Commons HttpClient component did not verify that the server
hostname matched the domain name in the subject's Common Name (CN) or
subjectAltName field in X.509 certificates. This could allow a
man-in-the-middle attacker to spoof an SSL server if they had a certificate
that was valid for any domain name. (CVE-2012-5783)

A flaw in JRuby's JSON gem allowed remote attacks by creating different
types of malicious objects. For example, it could initiate a denial of
service attack through resource consumption by using a JSON document to
create arbitrary Ruby symbols, which were never garbage collected. It could
also be exploited to create internal objects which could allow a SQL
injection attack. (CVE-2013-0269)

It was discovered that JRuby's REXML library did not properly restrict XML
entity expansion. An attacker could use this flaw to cause a denial of
service by tricking a Ruby application using REXML to read text nodes from
specially-crafted XML content, which will result in REXML consuming large
amounts of system memory. (CVE-2013-1821)

Note: Red Hat JBoss SOA Platform only provides JRuby as a dependency of
the scripting_chain quickstart example application. The CVE-2013-0269 and
CVE-2013-1821 flaws are not exposed unless the version of JRuby shipped
with that quickstart is used by a deployed, custom application.

Red Hat would like to thank Ruby on Rails upstream for reporting
CVE-2013-0269. Upstream acknowledges Thomas Hollstegge of Zweitag and Ben
Murphy as the original reporters of CVE-2013-0269.

Warning: Before applying the update, back up your existing Red Hat JBoss
SOA Platform installation (including its databases, applications,
configuration files, and so on).

All users of Red Hat JBoss SOA Platform 5.3.1 as provided from the Red
Hat Customer Portal are advised to apply this roll up patch.

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 SOA Platform installation (including its
databases, applications, configuration files, and so on).

Note that it is recommended to halt the Red Hat JBoss SOA Platform
server by stopping the JBoss Application Server process before installing
this update, and then after installing the update, restart the Red Hat
JBoss SOA Platform server by starting the JBoss Application Server
process.

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

873317 - CVE-2012-5783 jakarta-commons-httpclient: missing connection hostname check against X.509 certificate name
909029 - CVE-2013-0269 rubygem-json: Denial of Service and SQL Injection
