Summary: 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 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. 2. Relevant releases/architectures: Red Hat OpenStack Platform 16.2 - noarch 3. Description: Neutron is a virtual network service for OpenStack. Just like OpenStack Nova provides an API to dynamically request and configure virtual servers, Neutron provides an API to dynamically request and configure virtual networks. These networks connect "interfaces" from other OpenStack services (e.g., virtual NICs from Nova VMs). The Neutron API supports extensions to provide advanced network capabilities (e.g., QoS, ACLs, network, monitoring, etc.). Security Fix(es): * arbitrary dnsmasq reconfiguration via extra_dhcp_opts (CVE-2021-40085) 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. 4.
