Red Hat Security Advisory: openstack-neutron security update

Notes

Topic
An update for openstack-neutron is now available for Red Hat OpenStack Platform 14.0 (Rocky). Red Hat Product Security has rated this update as having a security impact of Important. 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 pluggable, scalable, and API-driven system that provisions networking services to virtual machines. Its main function is to manage connectivity to and from virtual machines. Security Fix(es): * openstack-neutron: incorrect validation of port settings in iptables security group driver (CVE-2019-9735) * openstack-neutron: DOS via broken port range merging in security group (CVE-2019-10876) 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.

By creating two security groups with separate/overlapping port ranges, an authenticated user may prevent Neutron from being able to configure networks on any compute nodes where those security groups are present, because of an Open vSwitch (OVS) firewall KeyError. All Neutron deployments utilizing neutron-openvswitch-agent are affected.",
