H Authorization Bypass Through User-Controlled Key neutron is an OpenStack project to provide “network connectivity as a service” between interface devices (e.g., vNICs) managed by other OpenStack services (e.g., nova). It implements the Neutron API. Affected versions of this package are vulnerable to Authorization Bypass Through User-Controlled Key in the process of creating or updating a port on a shared network by setting the `device_owner` field to a value beginning with "network:". An attacker can gain unauthorized network-service port privileges by exploiting default RBAC policies, which do not require network ownership for certain actions. This can allow bypassing anti-spoofing and security group protections, enabling DHCP, MAC, or IP spoofing against other tenants on the shared network, potentially resulting in information disclosure or disruption of network services. How to fix Authorization Bypass Through User-Controlled Key? A fix was pushed into the `master` branch but not yet published.	[25.0.0,)
M Denial of Service (DoS) neutron is an OpenStack project to provide “network connectivity as a service” between interface devices (e.g., vNICs) managed by other OpenStack services (e.g., nova). It implements the Neutron API. Affected versions of this package are vulnerable to Denial of Service (DoS) due to allowing the unrestricted creation of security groups, which allows users to query a list of security groups for an invalid project and exceed their querying quota. NOTE: This vulnerability exists due to an insufficient fix for CVE-2022-3277. How to fix Denial of Service (DoS)? There is no fixed version for `neutron`.	[0,)
