two enhancements are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

3. Description:
Luci is a web-based high availability administration application.
A flaw was found in the way the luci service was initialized. If a system
administrator started the luci service from a directory that was writable
to by a local user, that user could use this flaw to execute arbitrary code
as the root or luci user. (CVE-2013-4482)
A flaw was found in the way luci generated its configuration file. The file
was created as world readable for a short period of time, allowing a local
user to gain access to the authentication secrets stored in the
configuration file. (CVE-2013-4481)
These issues were discovered by Jan Pokorný of Red Hat.
These updated luci packages include numerous bug fixes and two
enhancements. Space precludes documenting all of these changes in this
advisory. Users are directed to the Red Hat Enterprise Linux 6.5 Technical
Notes, linked to in the References, 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. After installing this update, the luci service will be
restarted automatically.
