Topic

Updated luci packages that fix one security issue, several bugs, and add
various enhancements are now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Moderate 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

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.
(CVE-2014-3593)

This issue was discovered by Jan Pokorný 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.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
