Synopsis

The remote Red Hat host is missing a security update for Red Hat OpenStack Platform 16.2 (openstack-nova).

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2022:0999 advisory.

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)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
