## Overview

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.

## Affected packages

- `neutron >= 19.0.0.0rc1, < 19.5.0`
- `neutron < 18.6.0`
- `neutron >= 20.0.0.0rc1, < 20.3.0`

## Remediation

Upgrade to a patched release:

- `neutron 19.5.0`
- `neutron 18.6.0`
- `neutron 20.3.0`
