Updated JBoss Enterprise Application Platform (JBEAP) 4.3 packages that fix
three security issues and multiple bugs are now available for Red Hat
Enterprise Linux 5 as JBEAP 4.3.0.CP09.

scores, which give detailed severity ratings, are available for each

Description

JBoss Enterprise Application Platform is the market leading platform for
innovative and scalable Java applications; integrating the JBoss
Application Server, with JBoss Hibernate and JBoss Seam into a complete,
simple enterprise solution.

This release of JBEAP for Red Hat Enterprise Linux 5 serves as a
replacement to JBEAP 4.3.0.CP08.

These updated packages include multiple bug fixes which are detailed in the
Release Notes. The Release Notes will be available shortly from the link in
the References section.

The following security issues are also fixed with this release:

An input sanitization flaw was found in the way JBoss Drools implemented
certain rule base serialization. If a remote attacker supplied
specially-crafted input to a JBoss Seam based application that accepts
serialized input, it could lead to arbitrary code execution with the
privileges of the JBoss server process. (CVE-2010-3708)

A Cross-Site Request Forgery (CSRF) flaw was found in the JMX Console. A
remote attacker could use this flaw to deploy a WAR file of their choosing
on the target server, if they are able to trick a user, who is logged into
the JMX Console as the admin user, into visiting a specially-crafted web
page. (CVE-2010-3878)

A flaw was found in the JBoss Remoting component. A remote attacker could
use specially-crafted input to cause the JBoss Remoting listeners to become
unresponsive, resulting in a denial of service condition for services
communicating via JBoss Remoting sockets. (CVE-2010-3862)

Red Hat would like to thank Ole Husgaard of eXerp.com for reporting the
CVE-2010-3862 issue.

Warning: Before applying this update, please backup the JBEAP
"server/[configuration]/deploy/" directory, and any other customized
