"The remote Red Hat host is missing one or more security updates for RHV Manager.");
  script_set_attribute(attribute:"description", value:
"The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2021:2179 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.

    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-lodash: command injection via template (CVE-2021-23337)

    * nodejs-lodash: ReDoS via the toNumber, trim and trimEnd functions (CVE-2020-28500)

    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):

    * This release adds the queue attribute to the virtio-scsi driver in the virtual machine configuration.
    This improvement enables multi-queue performance with the virtio-scsi driver. (BZ#911394)

    * With this release, source-load-balancing has been added as a new sub-option for xmit_hash_policy. It can
    be configured for bond modes balance-xor (2), 802.3ad (4) and balance-tlb (5), by specifying
    xmit_hash_policy=vlan+srcmac. (BZ#1683987)

    * The default DataCenter/Cluster will be set to compatibility level 4.6 on new installations of Red Hat
    Virtualization 4.4.6.; (BZ#1950348)

    * With this release, support has been added for copying disks between regular Storage Domains and Managed
    Block Storage Domains.
    It is now possible to migrate disks between Managed Block Storage Domains and regular Storage Domains.
    (BZ#1906074)

    * Previously, the engine-config value LiveSnapshotPerformFreezeInEngine was set by default to false and
    was supposed to be uses in cluster compatibility levels below 4.4. The value was set to general version.
    With this release, each cluster level has it's own value, defaulting to false for 4.4 and above. This will
    reduce unnecessary overhead in removing time outs of the file system freeze command. (BZ#1932284)

    * With this release, running virtual machines is supported for up to 16TB of RAM on x86_64 architectures.
    (BZ#1944723)

    * This release adds the gathering of oVirt/RHV related certificates to allow easier debugging of issues
    for faster customer help and issue resolution.
    Information from certificates is now included as part of the sosreport. Note that no corresponding private
    key information is gathered, due to security considerations. (BZ#1845877)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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