Detail

Problem Description:

Updated python-django-horizon and python-django-openstack-auth packages that fix one security issue and multiple bugs are now available for Red Hat Enterprise Linux OpenStack Platform 5.0 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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux OpenStack Platform 5.0 for RHEL 6 - noarch

3. Description:

OpenStack Dashboard (horizon) provides administrators and users a graphical interface to access, provision and automate cloud-based resources. The dashboard allows cloud administrators to get an overall view of the size and state of the cloud and it provides end-users a self-service portal to provision their own resources within the limits set by administrators.

A denial of service flaw was found in the OpenStack Dashboard (horizon) when using the db or memcached session engine. An attacker could make repeated requests to the login page, which would result in a large number of unwanted backend session entries, possibly leading to a denial of service. (CVE-2014-8124)

Red Hat would like to thank the OpenStack Project for reporting this issue. Upstream acknowledges Eric Peterson from Time Warner Cable as the original reporter.

The python-django-horizon packages have been upgraded to upstream version 2014.1.4, which provides a number of bug fixes over the previous version, including:

* Default 'target={}' value leaks into subsequent 'policy.check()' calls. * Neutron subnet create tooltip has invalid HTML tags. * Memory reported improperly in admin dashboard. * The container dashboard does not handle unicode URL correctly. (BZ#1203281)

This update also fixes the following bugs:

* The option 'OPENSTACK_SSL_NO_VERIFY' is used to enable or disable checks for SSL certificate validity. Prior to this update, swift clients ignored this check. As a result, you could not use horizon with swift, and swift was accessed via a self signed certificate. With this update, the option is now handled properly and Horizon is able to use this endpoint while the 'OPENSTACK_SSL_NO_VERIFY' option is enabled. (BZ#1192517)

* Previously, horizon.log was not truncated automatically, resulting in very large log files. With this update, files are now trimmed by logrotate, fixing this issue. (BZ#1112621)

All OpenStack Dashboard users are advised to upgrade to these updated packages, which correct these issues.

4. Solution:

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