Updated struts packages that fix one security issue are now available for
Red Hat Network Satellite 5.4 and 5.5, and Red Hat Satellite 5.6.

Important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the

Description

Red Hat Satellite is a systems management tool for Linux-based
infrastructures. It allows for provisioning, monitoring, and remote
management of multiple Linux deployments with a single, centralized tool.

Apache Struts is a framework for building web applications with Java.

It was found that the Struts 1 ActionForm object allowed access to the
'class' parameter, which is directly mapped to the getClass() method. A
remote attacker could use this flaw to manipulate the ClassLoader used by
an application server running Struts 1. This could lead to remote code
execution under certain conditions. (CVE-2014-0114)

All Satellite users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. For this update to take
effect, the tomcat6 service must be restarted ("service tomcat6 restart").

Solution

Before applying this update, make sure all previously released errata
