"The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in
the RHSA-2023:4283 advisory.

    OpenStack Networking (neutron) is a virtual network service for OpenStack. Just as OpenStack Compute
    (nova) provides an API to dynamically request and
    configure virtual servers, OpenStack Networking provides an API to dynamically request and configure
    virtual networks. These networks connect 'interfaces' from other OpenStack services (e.g. virtual NICs
    from Compute VMs). The OpenStack Networking API supports extensions to provide advanced network
    capabilities (e.g. QoS, ACLs, network monitoring, etc.)

    Security Fix(es):

    * openstack-neutron: unrestricted creation of security groups (fix for CVE-2022-3277) (CVE-2023-3637)

    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):

    * Multiple patches missing from 16.2.4 to 16.2.5 (BZ#2219790)

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
