RHSA-2021:1518 - Security Advisory

Topic

An update is now available for Red Hat Ceph Storage 3.3 - Extended Life Support on Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. 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

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.
