-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: openstack-neutron security and bug fix update Advisory ID: RHSA-2018:2715-01 Product: Red Hat Enterprise Linux OpenStack Platform Advisory URL: https://access.redhat.com/errata/RHSA-2018:2715 Issue date: 2018-09-17 CVE Names: CVE-2018-14635 ==================================================================== 1. Summary: An update for openstack-neutron is now available for Red Hat OpenStack Platform 10.0 (Newton). 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. 2. Relevant releases/architectures: Red Hat OpenStack Platform 10.0 - noarch 3. Description: 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 issue, including the impact, a CVSS score, and other related information, refer to the CVE page listed in the References section. Bug Fix(es): * A new configuration option bridge_mac_table_size has been added for the neutron OVS agent. This value is set on every Open vSwitch bridge managed by the openvswitch-neutron-agent. The value controls the maximum number of MAC addresses that can be learned on a bridge. The default value for this new option is 50,000, which should be enough for most systems. Values outside a reasonable range (10 to 1,000,000) might be overridden by Open vSwitch. (BZ#1589031) * Previously, when a VM was destroyed, the IPv6 lease was not removed from dnsmasq lease files due to a missing dhcp_release6 binary. With this update, the dhcp_release6 binary is now provided in an updated dnsmasq-utils package version. (BZ#1545006) 4.
