1. Summary:

An update for JBoss Enterprise BRMS Platform 5.3.1, JBoss Enterprise Portal
Platform 4.3.0 CP07 and 5.2.2, and JBoss Enterprise SOA Platform 4.2.0
CP05, and 4.3.0 CP05 which 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 BRMS Platform is a business rules management system for
the management, storage, creation, modification, and deployment of JBoss
Rules. JBoss Enterprise Portal Platform is the open source implementation
of the Java EE suite of services and Portal services running atop JBoss
Enterprise Application Platform. JBoss Enterprise SOA Platform is the
next-generation ESB and business process automation infrastructure.

When using LDAP authentication with the provided LDAP login modules
(LdapLoginModule/LdapExtLoginModule), empty passwords were allowed by
default. An attacker could use this flaw to bypass intended authentication
by providing an empty password for a valid username, as the LDAP server may
recognize this as an 'unauthenticated authentication' (RFC 4513). This
update sets the allowEmptyPasswords option for the LDAP login modules to
false if the option is not already configured. (CVE-2012-5629)

Warning: Before applying this update, back up your JBoss installation,
including any databases, database settings, applications, configuration
files, and so on.

All users of JBoss Enterprise BRMS Platform 5.3.1, JBoss Enterprise Portal
Platform 4.3.0 CP07 and 5.2.2, and JBoss Enterprise SOA Platform 4.2.0
CP05, and 4.3.0 CP05 as provided from the Red Hat Customer Portal are
advised to apply this update.

3. Solution:

The References section of this erratum contains download links (you must
log in to download the update). Before applying this update, back up your
JBoss installation, including any databases, database settings,
applications, configuration files, and so on.

For JBoss Enterprise BRMS Platform, JBoss Enterprise Portal Platform, and
JBoss Enterprise SOA Platform, it is recommended to halt the server by
stopping the JBoss Application Server process before installing this
update, and then after installing the update, restart the server by
starting the JBoss Application Server process.
