"The remote Red Hat host is missing one or more security updates for Red Hat Virtualization.");
  script_set_attribute(attribute:"description", value:
"The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as
referenced in the RHSA-2023:3771 advisory.

    The VDSM service is required by a Virtualization Manager to manage the Linux hosts. VDSM manages and
    monitors the host's storage, memory and networks as well as virtual machine creation, other host
    administration tasks, statistics gathering, and log collection.

    The following packages have been upgraded to a later upstream version: ovirt-dependencies (4.5.3), ovirt-
    engine (4.5.3.8), vdsm (4.50.3.8). (BZ#2180717)

    Security Fix(es):

    * springframework: Security Bypass With Un-Prefixed Double Wildcard Pattern (CVE-2023-20860)

    * springframework: Spring Expression DoS Vulnerability (CVE-2023-20861)

    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, a host with Secure Intel Icelake Server Family could become non-operational because it did
    not provide the taa-no CPU feature.
    In this release, the check has been fixed in the Manager, and such hosts work properly. (BZ#2184623)

    * Previously, when creating bonds on a host outside the Manager and adding the host without starting it,
    the Rx\Tx drop count is shown as null.
    As a result, a Null Pointer Exception is thrown in the Administration Portal > Compute > Hosts > Network
    Interfaces tab.
    With this release, null values are accepted, and there are no exceptions displayed in the Network
    Interfaces tab. (BZ#2180230)

    * Previously, the Volume Extend Logic method skipped sparse volumes. As a result,  RAW sparse volumes (on
    file storage) were not extended properly.
    In this release, RAW sparse volumes are extended as expected. (BZ#2210036)

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.");
