(RHSA-2012:1022) Important: jbossas security update

JBoss Application Server is the base package for JBoss Enterprise
Application Platform, providing the core server components. The Java Naming
and Directory Interface (JNDI) Java API allows Java software clients to
locate objects or services in an application server.

It was found that the JBoss JNDI service allowed unauthenticated, remote
write access by default. The JNDI and HA-JNDI services, and the
HAJNDIFactory invoker servlet were all affected. A remote attacker able to
access the JNDI service (port 1099), HA-JNDI service (port 1100), or the
HAJNDIFactory invoker servlet on a JBoss server could use this flaw to add,
delete, and modify items in the JNDI tree. This could have various,
application-specific impacts. (CVE-2011-4605)

Red Hat would like to thank Christian Schlüter (VIADA) for reporting this
issue.

Warning: Before applying this update, back up your JBoss Enterprise
Application Platform’s “jboss-as/server/[PROFILE]/deploy/” directory, along
with all other customized configuration files.

All users of JBoss Enterprise Application Platform 5.1.2 as provided from
the Red Hat Customer Portal are advised to install this update.
