RHSA-2012:1025 - Security Advisory

Topic

Updated jbossas packages that fix one security issue are now available for
JBoss Enterprise Application Platform 4.3.0 CP10 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.

Description

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 "server/[PROFILE]/deploy/" directory, along with all
other customized configuration files.

Users of JBoss Enterprise Application Platform 4.3.0 CP10 on Red Hat
Enterprise Linux 4 and 5 should upgrade to these updated packages, which
correct this issue. The JBoss server process must be restarted for this
update to take effect.
