"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2019:2652 advisory.

    OpenStack Compute (nova) launches and schedules large networks of virtual machines, creating a redundant
    and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to
    orchestrate a cloud, including running virtual machine instances and controlling access through users and
    projects.

    Security Fix(es):

    * openstack-nova: Nova server resource faults leak external exception details (CVE-2019-14433)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and
    other related information, refer to the CVE page listed in the References section.

    Bug Fix(es):

    * [OSP14] 'hw_vif_model' image metadata property should be ignored for SR-IOV-based VIFs (BZ#1724122)

    * [OSP14] Snapshot image of shelved instance, using rbd backend for glance and nova, remains due to an
    exception after unshelving. (BZ#1725708)

    * Before, a REVERT_RESIZE operation could fail if using the iptables_hybrid firewall driver. This would
    happen due to Neutron sending the network-vif-plugged external event before Nova starts to listen for it.
    Now, Nova will start listening for network-vif-plugged external event based on the characteristics of the
    port. In the case of an OVS hybrid plug, it will start listening before sending the port binding request
    to Neutron. (BZ#1730728)

    * [OSP14] Evacuation takes more than 2 hours with 109 instances depending on number of NIC on destination.
    (BZ#1732880)
