RHSA-2022:8870 - Security Advisory

Topic

An update for openstack-neutron is now available for Red Hat OpenStack
Platform 16.1.9 (Train) for Red Hat Enterprise Linux (RHEL) 8.2.

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.

Description

OpenStack Networking (neutron) is a virtual network service for OpenStack.
Just as OpenStack Compute (nova) provides an API to dynamically request and
configure virtual servers, OpenStack Networking provides an API to
dynamically request and configure virtual networks. These networks connect
'interfaces' from other OpenStack services (e.g. virtual NICs from Compute
VMs). The OpenStack Networking API supports extensions to provide advanced
network capabilities (e.g. QoS, ACLs, network monitoring, etc.)

Security Fix(es):

• unrestricted creation of security groups (CVE-2022-3277)

For more details about the security issue(s), including the impact, a CVSS
