OpenStack Dashboard (Horizon) before 2014.1.3 and 2014.2.x before 2014.2.1 does not properly handle session records when using a db or memcached session engine, which allows remote attackers to cause a denial of service via a large number of requests to the login page.

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2015:0845 advisory.

    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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

OpenStack Dashboard was updated to fix bugs and security issues.
