1. Summary:

Updated JBoss Enterprise Application Platform (JBEAP) 4.2 packages that fix
three security issues and multiple bugs are now available for Red Hat
Enterprise Linux 5 as JBEAP 4.2.0.CP09.

The Red Hat Security Response Team has rated this update as having critical
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

2. Relevant releases/architectures:

JBoss Enterprise Application Platform for RHEL 5 Server - noarch

3. 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 4.2.0.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:

The JMX Console configuration only specified an authentication requirement
for requests that used the GET and POST HTTP "verbs". A remote attacker
could create an HTTP request that does not specify GET or POST, causing it
to be executed by the default GET handler without authentication. This
release contains a JMX Console with an updated configuration that no longer
specifies the HTTP verbs. This means that the authentication requirement is
applied to all requests. (CVE-2010-0738)

For the CVE-2010-0738 issue, if an immediate upgrade is not possible or the
server deployment has been customized, a manual fix can be applied. Refer
to the "Security" subsection of the "Issues fixed in this release" section
(JBPAPP-3952) of the JBEAP Release Notes, linked to in the References, for
details. Contact Red Hat JBoss Support for advice before making the changes
noted in the Release Notes.

Red Hat would like to thank Stefano Di Paola and Giorgio Fedon of Minded
Security for responsibly reporting the CVE-2010-0738 issue.

Unauthenticated access to the JBoss Application Server Web Console
(/web-console) is blocked by default. However, it was found that this block
was incomplete, and only blocked GET and POST HTTP verbs. A remote attacker
could use this flaw to gain access to sensitive information. This release
contains a Web Console with an updated configuration that now blocks all
unauthenticated access to it by default. (CVE-2010-1428)

The RHSA-2008:0827 update fixed an issue (CVE-2008-3273) where
unauthenticated users were able to access the status servlet; however, a
bug fix included in the RHSA-2009:0348 update re-introduced the issue. A
remote attacker could use this flaw to acquire details about deployed web
contexts. (CVE-2010-1429)

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

All users of JBEAP 4.2 on Red Hat Enterprise Linux 5 are advised to upgrade
to these updated packages.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
