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
