"The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2013:1525 advisory.

    The openstack-glance packages provide a service (code name Glance) that
    acts as a registry for virtual machine images.

    A flaw was found in the Glance download_image policy enforcement for cached
    system images. When an image was previously cached by an authorized
    download, any authenticated user able to determine the image by its UUID
    could download that image, bypassing the download_image policy. Only setups
    making use of the download_image policy were affected. (CVE-2013-4428)

    Red Hat would like to thank the OpenStack Project for reporting this
    issue. The OpenStack Project acknowledges Stuart McLaren from HP as the
    original reporter.

    These updated openstack-glance packages have been upgraded to upstream
    version 2013.1.4, which provides a number of bug fixes over the previous
    version. (BZ#1021640)

    All users of openstack-glance are advised to upgrade to these updated
    packages, which correct these issues. After installing the updated
    packages, the running Glance services must be manually restarted (using
    service [service name] restart) for this update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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