Red Hat Security Advisory
Synopsis: Important: mod_cluster-native security update
Advisory ID: RHSA-2012:0035-01
Product: JBoss Enterprise Web Server
Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0035.html
Issue date: 2012-01-18
CVE Names: CVE-2011-4608
=====================================================================
1. Summary:
Updated mod_cluster packages that fix one security issue are now available
for JBoss Enterprise Web Server 1.0.2 for Red Hat Enterprise Linux 4, 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.
2. Relevant releases/architectures:
JBoss Enterprise Web Server 1.0 for RHEL 4 AS - i386, noarch, x86_64
JBoss Enterprise Web Server 1.0 for RHEL 4 ES - i386, noarch, x86_64
JBoss Enterprise Web Server 1.0 for RHEL 5 Server - i386, noarch, x86_64
JBoss Enterprise Web Server 1.0 for RHEL 6 Server - i386, noarch, x86_64
3. Description:
mod_cluster-native provides a native build of mod_cluster for the Apache
HTTP Server (httpd). mod_cluster is an httpd-based load balancer. Like
mod_jk, it uses a communication channel to forward requests from httpd to
an application server node.
It was found that mod_cluster allowed worker nodes to register on any
virtual host (vhost), regardless of the security constraints applied to
other vhosts. In a typical environment, there will be one vhost configured
internally for worker nodes, and another configured externally for serving
content. A remote attacker could use this flaw to register an
attacker-controlled worker node via an external vhost that is not
configured to apply security constraints, then use that worker node to
serve malicious content, intercept credentials, and hijack user sessions.
(CVE-2011-4608)
This update also upgrades mod_cluster to version 1.0.10.GA_CP02.
Users of mod_cluster should upgrade to these updated packages, which
resolve this issue. After installing the updated packages, Red Hat
Enterprise Linux 4 users must restart the httpd22 service, and Red Hat
Enterprise Linux 5 and 6 users must restart the httpd service, for the
update to take effect.
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
https://access.redhat.com/kb/docs/DOC-11259
5. Bugs fixed (http://bugzilla.redhat.com/):

Red Hat Security Advisory
Synopsis: Important: mod_cluster-native security update
Advisory ID: RHSA-2012:0040-01
Product: JBoss Enterprise Web Platform
Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0040.html
Issue date: 2012-01-18
CVE Names: CVE-2011-4608
=====================================================================
1. Summary:
An update for the Native components for JBoss Enterprise Web Platform 5.1.2
that fixes one security issue is now available from the Red Hat Customer
Portal.
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.
2. Description:
Part of the Native components for JBoss Enterprise Web Platform is
mod_cluster, an Apache HTTP Server (httpd) based load balancer. Like
mod_jk, it uses a communication channel to forward requests from httpd to
an application server node.
It was found that mod_cluster allowed worker nodes to register on any
virtual host (vhost), regardless of the security constraints applied to
other vhosts. In a typical environment, there will be one vhost configured
internally for worker nodes, and another configured externally for serving
content. A remote attacker could use this flaw to register an
attacker-controlled worker node via an external vhost that is not
configured to apply security constraints, then use that worker node to
serve malicious content, intercept credentials, and hijack user sessions.
(CVE-2011-4608)
All users of JBoss Enterprise Web Platform 5.1.2 as provided from the Red
Hat Customer Portal are advised to apply this update. Refer to the Solution
section for installation instructions.
3. Solution:
The References section of this erratum contains a download link (you
must log in to download the update). To apply the update:
1) Download the update for the Native components for JBoss Enterprise
Web Platform 5.1.2.
2) Copy the Apache HTTP Server modules provided by the update to your
JBoss Enterprise Web Server front-end.
3) Restart the Apache HTTP Server on your JBoss Enterprise Web Server
front-end.
Refer to the "Install proxy server components" section of the HTTP
Connectors Load Balancing Guide for JBoss Enterprise Application
Platform 5, available from docs.redhat.com, for further information
(JBoss Enterprise Web Platform is a subset of JBoss Enterprise
Application Platform).
