Topic

An updated katello-configure package that fixes one security issue is now
available for Red Hat Subscription Asset Manager.

Red Hat Product Security 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.

Description

The katello-configure package provides the katello-configure script, which
configures the Katello installation, and the katello-upgrade script, which
handles upgrades between versions.

It was discovered that the default configuration of Elasticsearch enabled
dynamic scripting, allowing a remote attacker to execute arbitrary MVEL
expressions and Java code via the source parameter passed to _search.
(CVE-2014-3120)

All Subscription Asset Manager users are advised to upgrade to this updated
package. The update provides a script that modifies the elasticsearch.yml
configuration file to disable dynamic scripting. After updating, run the
"katello-configure" command. This will update the elasticsearch.yml
configuration file and restart the elasticsearch service.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied. After updating, run the
"katello-configure" command to apply the needed configuration changes.
