"Updated JBoss Enterprise Application Platform 4.3.0 CP10 packages that
fix one security issue are now available for Red Hat Enterprise Linux
4 and 5.

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.

JBoss Enterprise Application Platform is a platform for Java
applications, which integrates the JBoss Application Server with JBoss
Hibernate and JBoss Seam.

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 Application Platform installation (including all
applications and configuration files).

All users of JBoss Enterprise Application Platform 4.3.0 CP10 on Red
Hat Enterprise Linux 4 and 5 are advised to upgrade to these updated
packages. The JBoss server process must be restarted for the update to
take effect."
