Topic

An update for Red Hat JBoss Operations Network 3.2.3 that fixes one security issue in the Apache commons-collections library is now available.

Red Hat Product Security has rated this update as having Critical 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 Operations Network provides an integrated solution for managing JBoss middleware, other network infrastructure, and applications built on Red Hat Enterprise Application Platform (EAP). The Apache Commons Collections library provides new interfaces, implementations, and utilities to extend the features of the Java Collections Framework.

It was found that the Apache commons-collections library permitted code execution when deserializing objects involving a specially constructed chain of classes. A remote attacker could use this flaw to execute arbitrary code with the permissions of the application using the commons-collections library. (CVE-2015-7501)

All users of JBoss Operations Network 3.2.3 as provided from the Red Hat Customer Portal are advised to apply this security update.

Solution

This is a server patch that contains a single fix and should not be mixed with other server patches. If you already have a server patch, please contact Red Hat Global Support Services for compatibility assessment.

You must shutdown the JBoss ON server prior to applying this patch.

This patch must be applied to each JBoss ON server in a high-availability (HA) environment. You can apply the patch to each server individually so that only one server is down at a time.

To install the patch: 1. Stop the JBoss ON server. 2. Backup and remove the following files:

        <RHQ_SERVER_HOME>/jbossas/modules/system/layers/base/org/apache/commons/collections/main/commons-collections-3.2.1-redhat-2.jar
        <RHQ_SERVER_HOME>/jbossas/modules/system/layers/base/org/apache/commons/collections/main/module.xml
        <RHQ_SERVER_HOME>/modules/org/rhq/server-startup/main/deployments/rhq.ear/lib/commons-collections-3.2.1.jar
        <RHQ_SERVER_HOME>/modules/org/rhq/server-startup/main/deployments/rhq.ear/rhq-portal.war/WEB-INF/lib/commons-collections-3.2.1.jar
        <RHQ_SERVER_HOME>/modules/org/rhq/server-startup/main/deployments/rhq.ear/rhq-content_http.war/WEB-INF/lib/commons-collections-3.2.1.jar

3.  Extract the patch archive to the JBoss ON server's home directory.

    For example:
        unzip -od "${RHQ_SERVER_HOME}" /tmp/BZ1282545.zip

    Be sure to replace any existing files if prompted.
4.  Start the JBoss ON server.

Repeat the steps for any remaining JBoss ON servers in a HA environment.

To uninstall the patch:
1.  Stop the JBoss ON server.
2.  Remove the updated files:

        <RHQ_SERVER_HOME>/jbossas/modules/system/layers/base/org/apache/commons/collections/main/commons-collections-3.2.1.redhat-3-bz-1281964.jar
        <RHQ_SERVER_HOME>/jbossas/modules/system/layers/base/org/apache/commons/collections/main/module.xml
        <RHQ_SERVER_HOME>/modules/org/rhq/server-startup/main/deployments/rhq.ear/lib/commons-collections-3.2.1.redhat-3-bz-1281964.jar
        <RHQ_SERVER_HOME>/modules/org/rhq/server-startup/main/deployments/rhq.ear/rhq-portal.war/WEB-INF/lib/commons-collections-3.2.1.redhat-3-bz-1281964.jar
        <RHQ_SERVER_HOME>/modules/org/rhq/server-startup/main/deployments/rhq.ear/rhq-content_http.war/WEB-INF/lib/commons-collections-3.2.1.redhat-3-bz-1281964.jar

3.  Restore the following files from the backup created prior to applying this patch:

        <RHQ_SERVER_HOME>/jbossas/modules/system/layers/base/org/apache/commons/collections/main/commons-collections-3.2.1-redhat-2.jar
        <RHQ_SERVER_HOME>/jbossas/modules/system/layers/base/org/apache/commons/collections/main/module.xml
        <RHQ_SERVER_HOME>/modules/org/rhq/server-startup/main/deployments/rhq.ear/lib/commons-collections-3.2.1.jar
        <RHQ_SERVER_HOME>/modules/org/rhq/server-startup/main/deployments/rhq.ear/rhq-portal.war/WEB-INF/lib/commons-collections-3.2.1.jar
        <RHQ_SERVER_HOME>/modules/org/rhq/server-startup/main/deployments/rhq.ear/rhq-content_http.war/WEB-INF/lib/commons-collections-3.2.1.jar

4.  Start the JBoss ON server.

Repeat the steps for any remaining JBoss ON servers in a HA environment.
