Luci is a web-based high availability administration application. It was discovered that luci used eval on inputs containing strings from the cluster configuration file when generating its web pages. An attacker with privileges to create or edit the cluster configuration could use this flaw to execute arbitrary code as the luci user on a host running luci. This issue was discovered by Jan Pokorny of Red Hat. These updated luci packages also include several bug fixes and multiple enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.6 Technical Notes, linked to in the References section, for information on the most significant of these changes. All luci users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements.
