Alpine: ceph16: security update to 16.2.3-r0

high Tenable Cloud Security Plugin ID 403795

Description

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

 - An authentication flaw was found in ceph in versions before 14.2.20. 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 ones. The highest threat
 from this vulnerability is to data confidentiality and integrity as well as system availability.
 (CVE-2021-20288)
