Echo: ceph: security update to 20.2.4+ds-1

critical Tenable Cloud Security Plugin ID 478673

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Ceph is an open-source distributed storage platform providing object, block, and file storage. In versions
 prior to 20.2.4 and 19.2.6, the Monitor subscription handler fails to properly authorize access to the
 configuration-key store, allowing any CephX user with only `mon allow r` capabilities to read the entire
 store by sending a single crafted MMonSubscribe message. The config-key store holds sensitive secrets
 including OSD LUKS disk-encryption passphrases and, on cephadm-managed clusters, the SSH private key that
 cephadm uses to reach every host in the cluster. Because that key grants root on every node under the
 default cephadm configuration, a low-privileged read-only account can escalate to full cluster and host
 compromise. This issue is fixed in versions 20.2.4 and 19.2.6 (CVE-2026-50152)

Solution

Update the ceph library and its related packages to version 20.2.4+ds-1 or later.
