Mageia 8: MGASA-2021-0207 Moderate: Ceph Key Reuse Threat

An authentication flaw was found in ceph. When the monitor handles CEPHX_GET_AUTH_SESSION_KEY requests, it doesn't sanitize other_keys, allowing key reuse. An attacker who can request a global_id can exploit the ability of any user to request a global_id previously associated with another user, as ceph does not force the reuse of old keys to generate new .
