Solution

https://access.redhat.com/articles/11258

Summary

Red Hat Ceph Storage is a scalable, open, software-defined storage platform that combines the most stable version of the Ceph storage system with a Ceph management platform, deployment utilities, and support services.
The ceph-ansible package provides Ansible playbooks for installing, maintaining, and upgrading Red Hat Ceph Storage.
Grafana is an open source, feature rich metrics dashboard and graph editor for Graphite, InfluxDB & OpenTSDB.
The tcmu-runner packages provide a service that handles the complexity of the LIO kernel target's userspace passthrough interface (TCMU). It presents a C plugin API for extension modules that handle SCSI requests in ways not possible or suitable to be handled by LIO's in-kernel backstores.
Security Fix(es):
* grafana: SSRF incorrect access control vulnerability allows unauthenticated users to make grafana send HTTP requests to any URL (CVE-2020-13379)
* ceph: User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila (CVE-2020-27781)
* tcmu-runner: SCSI target (LIO) write to any block on ILO backstore (CVE-2021-3139)
* ceph: specially crafted XML payload on POST requests leads to DoS by crashing RGW (CVE-2020-12059)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
This advisory fixes the following bug:
* When rebooting OSDs, the `_OSD down_` tab in the `_CEPH Backend storage_` dashboard shows the correct number of OSDs that is `down`. However, when all OSDs are `up` again after the reboot, the tab continues showing the number of `down` OSDs. With this update, both CLI and Grafana values are matching during osd up/down operation and working as expected. (BZ#1652233)
All users of Red Hat Ceph Storage are advised to upgrade to these updated packages.
