"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2018:3754 advisory.

    Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution
    designed for on-premise or private cloud deployments.

    Security Fix(es):

    * A privilege escalation vulnerability exists in OpenShift Container Platform 3.x which allows for
    compromise of pods running on a compute node to which a pod is scheduled with normal user privilege. This
    access could include access to all secrets, pods, environment variables, running pod/container processes,
    and persistent volumes, including in privileged containers. Additionally, on versions 3.6 and higher of
    OpenShift Container Platform, this vulnerability allows cluster-admin level access to any API hosted by an
    aggregated API server. This includes the servicecatalog API which is installed by default in 3.7 and
    later. Cluster-admin level access to the service catalog allows creation of brokered services by an
    unauthenticated user with escalated privileges in any namespace and on any node. This could lead to an
    attacker being allowed to deploy malicious code, or alter existing services. (CVE-2018-1002105)

    This advisory contains the RPM packages for Red Hat OpenShift Container Platform 3.3. See the following
    advisory for the container images for this release:

    https://access.redhat.com/errata/RHBA-2018:3753

    https://docs.openshift.com/container-platform/3.3/release_notes/ocp_3_3_release_notes.html

    All OpenShift Container Platform 3.3 users are advised to upgrade to these updated packages and images.

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.");
