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 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.

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
