"The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2021:0383 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 Manager is a JBoss Application Server application that provides several interfaces through which the
    virtual environment can be accessed and interacted with, including an Administration Portal, a VM Portal,
    and a Representational State Transfer (REST) Application Programming Interface (API).

    Security Fix(es):

    * ovirt-engine: non-admin user is able to access other users public SSH key (CVE-2020-35497)

    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, you could not migrate the master role to a newer domain without migrating the virtual
    machines from the old domain and putting it into maintenance mode. Additionally, you could not put a
    hosted_storage domain into maintenance mode.

    With this release, you can use the REST API to move the master role to another storage domain without
    putting the domain into maintenance mode.

    For example, to set a storage domain with ID `456` as a master on a data center with ID `123`, send the
    following request:

    ----
    POST /ovirt-engine/api/datacenters/123/setmaster

    With a request body like this:

    <action>
      <storage_domain id=456/>
    </action>
    ----

    Alternatively, this example uses the name of the storage domain:

    ----
    <action>
      <storage_domain>
        <name>my-nfs</name>
      </storage_domain>
    </action>
    ----
    (BZ#1576923)

    * Previously when a virtual machine moved from one cluster to another, resulting in the virtual machine's
    chipset changing, then the virtual machine did not run successfully.

    With this release, when a virtual machine moves from one cluster to another, it's devices and chipset are
    automatically updated, and the virtual machine runs successfully. (BZ#1894454)

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.");
