1. Summary:

An updated jbosssx2 package for JBoss Enterprise Web Platform 5.2.0 that
fixes one security issue is now available for Red Hat Enterprise Linux 4,
5, and 6.

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. Relevant releases/architectures:

JBoss Enterprise Web Platform 5 for RHEL 4 AS - noarch
JBoss Enterprise Web Platform 5 for RHEL 4 ES - noarch
JBoss Enterprise Web Platform 5 for RHEL 5 Server - noarch
JBoss Enterprise Web Platform 5 for RHEL 6 Server - noarch

3. Description:

The Enterprise Web Platform is a slimmed down profile of the JBoss
Enterprise Application Platform intended for mid-size workloads with light
and rich Java applications.

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 existing JBoss
Enterprise Web Platform installation (including all applications and
configuration files).

All users of JBoss Enterprise Web Platform 5.2.0 on Red Hat Enterprise
Linux 4, 5, and 6 are advised to upgrade to this updated package. The JBoss
server process must be restarted for the update to take effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
