Summary
Red Hat Security Advisory: openstack-neutron security update

Notes

Topic
An update for openstack-neutron is now available for Red Hat OpenStack Platform 12.0 (Pike). 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 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: A router interface out of subnet IP range results in a denial of service (CVE-2018-14635) For more details about the security issues, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE pages listed in the References section.
