"The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as
referenced in the RHSA-2021:1186 advisory.

    The ovirt-engine package provides the manager for virtualization environments.
    This manager enables admins to define hosts and networks, as well as to add
    storage, create VMs and manage user permissions.

    Bug Fix(es):
    * Previously, saving user preferences in the Red Hat Virtualization Manager required the MANIPULATE_USERS
    permission level. As a result, user preferences were not saved on the server.
    In this release, the required permission level for saving user preferences was changed to EDIT_PROFILE,
    which is the permission level assigned by default to all users. As a result, saving user preferences works
    as expected. (BZ#1920539)

    A list of bugs fixed in this update is available in the Technical Notes
    book:

    https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.4/html-single/technical_notes

    Security Fix(es):

    * nodejs-bootstrap-select: not escaping title values on <option> may lead to XSS (CVE-2019-20921)

    * datatables.net: prototype pollution if 'constructor' were used in a data property name (CVE-2020-28458)

    other related information, refer to the CVE page(s) listed in the References section.
