"The remote Redhat Enterprise Linux 8 host has a package installed that is affected by a vulnerability as referenced in
the RHSA-2021:2866 advisory.

    The ovirt-engine package provides the Red Hat Virtualization Manager, a centralized management platform
    that allows system administrators to view and manage virtual machines. The Manager provides a
    comprehensive range of features including search capabilities, resource management, live migrations, and
    virtual infrastructure provisioning.

    The ovirt-ansible-hosted-engine-setup package provides an Ansible role for deploying Red Hat
    Virtualization Hosted-Engine.

    Security Fix(es):

    * ansible: multiple modules expose secured values (CVE-2021-3447)

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

    Bug Fix(es):

    * Previously, using an Ansible playbook to fetch virtual machine disk information was slow and incomplete,
    while the REST API fetched the information faster and more completely.
    In this release, the Ansible playbook fetches the information completely and quickly. (BZ#1947902)

    * The ovirt-engine in RHV 4.4.7 requires an Ansible 2.9.z version later than Ansible 2.9.20.
    In addition, in RHV 4.4.7 the version limitation for a specific Ansible version has been removed, the
    correct Ansible version is now shipped in the RHV subscription channels. (BZ#1966145)

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.");
