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

1. Summary:

An updated jboss-seam.jar file for JBoss Enterprise SOA Platform 4.3.0.CP05
and 5.1.0 that 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 SOA Platform is the next-generation ESB and business
process automation infrastructure. JBoss Enterprise 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.

It was found that the fix for CVE-2011-1484 was incomplete: JBoss Seam 2
did not block access to all malicious JBoss Expression Language (EL)
constructs in page exception handling, allowing arbitrary Java methods to
be executed. A remote attacker could use this flaw to execute arbitrary
code via a specially-crafted URL provided to certain applications based on
the JBoss Seam 2 framework. Note: A properly configured and enabled Java
Security Manager would prevent exploitation of this flaw. (CVE-2011-2196)

Red Hat would like to thank the ObjectWorks+ Development Team at Nomura
Research Institute for reporting this issue.

All users of JBoss Enterprise SOA Platform 4.3.0.CP05 and 5.1.0 as provided
from the Red Hat Customer Portal are advised to install this update. Refer
to the Solution section for information about installing the update.

3. Solution:

The References section of this erratum contains download links (you must
log in to download the updated file). Before applying the update, backup
your existing JBoss Enterprise SOA Platform installation (including its
databases, applications, configuration files, and so on).

Important: JBoss Enterprise SOA Platform 4.3.0.CP05 ships with both the
JBoss Seam and JBoss Seam 2 frameworks. Ensure you only replace version
2 with the updated jboss-seam.jar file.

If you have created custom applications that are packaged with a copy of
the JBoss Seam 2 library, those applications must be rebuilt with the
updated jboss-seam.jar file.

The JBoss Application Server process must be restarted for the update to
take effect.
