"The remote Red Hat host is missing one or more security updates for openstack-nova.");
  script_set_attribute(attribute:"description", value:
"The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2014:0112 advisory.

    The openstack-nova packages provide OpenStack Compute (nova), which
    provides services for provisioning, managing, and using virtual
    machine instances.

    It was discovered that enabling qpid_protocol = ssl in the nova.conf file
    did not result in nova using SSL to communicate to Qpid. If Qpid was not
    configured to enforce SSL this could lead to sensitive information being
    sent unencrypted over the communication channel. (CVE-2013-6491)

    A flaw was found in the way OpenStack Compute controlled the size of disk
    images. An authenticated remote user could use malicious compressed qcow2
    disk images to consume large amounts of disk space, potentially causing a
    denial of service on the OpenStack Compute nodes. (CVE-2013-4463)

    Red Hat would like to thank the OpenStack project for reporting
    CVE-2013-4463. Upstream acknowledges Bernhard M. Wiedemann of SuSE as the
    original reporter of this issue.

    This update also fixes the following bugs:

    * When using GroupAntiAffinityFilter, the scheduler was not filtering
    instances in the group, which could cause an instance to not be scheduled
    at all if a group was specified on boot. With this fix, groups are taken
    into account and the instance is scheduled as expected. (BZ#1014948)

    * If an exchange had not been created previously by a consumer, the
    publisher would crash because it could not find the specified exchange.
    This resulted from Qpid's direct publisher using the wrong exchange type
    'Direct'. With this fix, the exchange type in the publisher has been
    changed to 'direct'. (BZ#1042055)

    * Unhandled errors in the Qpid consuming thread could kill it silently and
    isolate the component from the rest of the system. To fix this, the
    consuming thread has been made more resilient to errors by ensuring it does
    not die on an unhandled error. Compute now logs the error and retries the
    consuming thread. (BZ#1050213)

    All openstack-nova users are advised to upgrade to these updated packages,
    which contain backported patches to correct these issues.

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

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