1. Summary:

An update for the Apache Commons Collections component that fixes one
security issue is now available from the Red Hat Customer Portal for Red
Hat JBoss Operations Network 3.3 update 4.

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.

2. Description:

Apache Commons Collections is a library built upon Java JDK classes by

arbitrary code with the permissions of the application using the
commons-collections library. (CVE-2015-7501)

Further information about this security flaw may be found at:
https://access.redhat.com/solutions/2045023

All users of JBoss Operations Network 3.3.4 as provided from the Red Hat
Customer Portal are advised to apply this security update.

3. Solution:

The References section of this erratum contains a download link (you must
log in to download the update). 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/col
lections/main/commons-collections-3.2.1.redhat-3.jar   
<RHQ_SERVER_HOME>/jbossas/modules/system/layers/base/org/apache/commons/col
lections/main/module.xml
<RHQ_SERVER_HOME>/modules/org/rhq/server-startup/main/deployments/rhq.ear/r
hq-portal.war/WEB-INF/lib/commons-collections-3.2.1.jar
<RHQ_SERVER_HOME>/modules/org/rhq/server-startup/main/deployments/rhq.ear/r
hq-content_http.war/WEB-INF/lib/commons-collections-3.2.1.jar
<RHQ_SERVER_HOME>/modules/org/rhq/server-startup/main/deployments/rhq.ear/l
ib/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/BZ1281514.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/col
lections/main/commons-collections-3.2.1.redhat-3-bz-1281962.jar
