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

1. Summary:

Updated JBoss Enterprise Application Platform 6.0.1 packages that fix one
security issue are now available for Red Hat Enterprise Linux 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 Application Platform 6 for RHEL 5 Server - noarch
JBoss Enterprise Application Platform 6 for RHEL 6 Server - noarch

3. Description:

JBoss Enterprise Application Platform 6 is a platform for Java applications
based on JBoss Application Server 7.

When using LDAP authentication with either the "ldap" configuration entry
or 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)

Note: If you are using the "ldap" configuration entry and rely on empty
passwords, they will no longer work after applying this update. The
jboss-as-domain-management module, by default, will prevent empty
passwords. This cannot be configured; however, a future release may add a
configuration option to allow empty passwords when using the "ldap"
configuration entry.

Warning: Before applying this update, back up your existing JBoss
Enterprise Application Platform installation and deployed applications.

All users of JBoss Enterprise Application Platform 6.0.1 on Red Hat
Enterprise Linux 5 and 6 are advised to upgrade to these updated packages.
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
