Summary

Red Hat Security Advisory: Red Hat OpenStack Platform 16.2 (openstack-neutron) security update

Notes

Topic

An update for openstack-neutron is now available for Red Hat OpenStack Platform 16.2 (Train). Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Details

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): * Routes middleware memory leak for nonexistent controllers (CVE-2021-40797) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section.

Summary

An issue was discovered in the routes middleware in OpenStack Neutron before 16.4.1, 17.x before 17.2.1, and 18.x before 18.1.1. By making API requests involving nonexistent controllers, an authenticated user may cause the API worker to consume increasing amounts of memory, resulting in API performance degradation or denial of service.
