1. Summary:

An update for openstack-nova is now available for Red Hat OpenStack
Platform 16.2 (Train).

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 16.2 - noarch

3. Description:

OpenStack Compute (codename Nova) is open source software designed
to provision and manage large networks of virtual machines,creating a
redundant and scalable cloud computing platform. It gives you the software,
control panels, and APIs required to orchestrate a cloud, including running
instances, managing networks, and controlling access through users and
projects.OpenStack Compute strives to be both hardware and hypervisor
agnostic, currently supporting a variety of standard hardware
configurations and seven major hypervisors.

Security Fix(es):

* novnc allows open redirection (CVE-2021-3654)

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.

Bug Fix(es):

* Red Hat OpenStack Platform (RHOSP) does not support the use of a fully
qualified domain name (FQDN) as the instance display name in a boot server
request. The instance display name is passed from the boot server request
to the `instance.hostname` field. Some customers use this unsupported
naming in their workflows.

A recent update [1] now sanitizes the `instance.hostname` field. The
sanitization steps include replacing periods with dashes, a replacement
that makes it impossible to continue using the unsupported FQDN instance
display names.

This update provides a temporary workaround for customers who use a fully
qualified domain name (FQDN) as the instance display name in a boot server
request. It limits the scope of the sanitization to cases where the
instance display name ends with a period followed by one or more numeric
digits.

If you use FQDN as the instance display name in a boot server request,
modify your workflow before upgrading to RHOSP 17. (BZ#2036652)
