Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

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.

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.
