An uncontrolled resource consumption flaw was found in openstack-neutron. This flaw allows a remote authenticated user to query a list of security groups for an invalid project. This issue creates resources that are unconstrained by the user's quota. If a malicious user were to submit a significant number of requests, this could lead to a denial of service.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

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.)
