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.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
