The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5866-1 advisory.

    It was discovered that Nova did not properly manage data logged into the log file. An attacker with read     access to the service's logs could exploit this issue and may obtain sensitive information. This issue     only affected Ubuntu 16.04 ESM and Ubuntu 18.04 LTS. (CVE-2015-9543)

    It was discovered that Nova did not properly handle attaching and reattaching the encrypted volume. An     attacker could possibly use this issue to perform a denial of service attack. This issue only affected     Ubuntu 16.04 ESM. (CVE-2017-18191)

    It was discovered that Nova did not properly handle the updation of domain XML after live migration. An     attacker could possibly use this issue to corrupt the volume or perform a denial of service attack. This     issue only affected Ubuntu 18.04 LTS. (CVE-2020-17376)

    It was discovered that Nova was not properly validating the URL passed to noVNC. An attacker could     possibly use this issue by providing malicious URL to the noVNC proxy to redirect to any desired URL. This     issue only affected Ubuntu 16.04 ESM and Ubuntu 18.04 LTS. (CVE-2021-3654)

    It was discovered that Nova did not properly handle changes in the neutron port of vnic_type type. An     authenticated user could possibly use this issue to perform a denial of service attack. This issue only     affected Ubuntu 20.04 LTS. (CVE-2022-37394)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:2714 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: Swapping encrypted volumes can allow an attacker to corrupt the LUKS header causing a     denial of service in the host (CVE-2017-18191)

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

    Bug Fix(es):

    * Previously, the MTU of TAP devices was not configured. As a result, the network could be configured with     a different MTU than a guest TAP device.

    With this update, you can configure libvirt when you create the TAP device for the guest. Nova passes the     correct parameter to libvirt, and the TAP device now has the same configuration as the network.
    (BZ#1553839)

    * Previously, the MTU of TAP devices was not configured. As a result, the network could be configured with     a different MTU than a guest TAP device.

    With this update, you can configure libvirt when you create the TAP device for the guest. Nova passes the     correct parameter to libvirt, and the TAP device now has the same configuration as the network.
    (BZ#1553559)

    * Previously, the '[vnc] keymap' option was 'en-us' by default, and it was not possible to unset this     configuration. As a result of this, non-US locales experienced ineffective key mappings.

    With this update, users can unset the '[vnc] keymap' value. In this case, the VNC client configures the     locale and non-US users attain more effective key mappings. (BZ#1441962)

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:2855 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: Swapping encrypted volumes can allow an attacker to corrupt the LUKS header causing a     denial of service in the host (CVE-2017-18191)

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

    Bug Fix(es):

    * This update fixes a race condition that could generate error messages and cause migration failures     during nova live migrations.

    Prior to this update, if a domain was already cleaned out by periodic tasks, undefining the domain source     during a live migration sometimes generated a Domain not found (Code=42) error. (BZ#1614325)
