Type/Severity

Security Advisory: Important

Topic

An update is now available for Red Hat Ceph Storage 4.2.

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.

This package contains a new implementation of the original libtirpc, transport-independent RPC (TI-RPC) library for NFS-Ganesha.

NFS-GANESHA is a NFS Server running in user space. It comes with various back-end modules (called FSALs) provided as shared objects to support different file systems and name-spaces.

Security Fix(es):

• ceph: User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila (CVE-2020-27781)
• ceph: CEPHX_V2 replay attack protection lost (CVE-2020-25660)
• ceph-ansible: insecure ownership on /etc/ceph/iscsi-gateway.conf configuration file (CVE-2020-25677)

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.
