- Update to security release of Samba 4.16 with update libldb to 2.5.3:
  + ldb wildcard matching makes excessive allocations (Samba#15331).

- Security fixes (Samba#15270, Samba#15315):
  + CVE-2023-0922: The Samba AD DC administration tool, when operating against a
                   remote LDAP server, will by default send new or reset
                   passwords over a signed-only connection.

  + CVE-2023-0614: The fix in 4.6.16, 4.7.9, 4.8.4 and 4.9.7 for CVE-2018-10919
                   Confidential attribute disclosure via LDAP filters was
                   insufficient and an attacker may be able to obtain
                   confidential BitLocker recovery keys from a Samba AD DC.
                   Installations with such secrets in their Samba AD should
                   assume they have been obtained and need replacing.

- Update to maintenance release of Samba 4.16 with fixes of the Samba CVE for
  the Windows Kerberos Elevation of Privilege Vulnerability disclosed by
  Microsoft on Nov 8 2022 (CVE-2022-37967, CVE-2022-37966).
- Security fixes:
  + CVE-2022-37966: A Samba Active Directory DC will issue weak rc4-hmac
                    session keys for use between modern clients and servers
                    despite all modern Kerberos implementations supporting
                    the aes256-cts-hmac-sha1-96 cipher.
                    On Samba Active Directory DCs and members
                    'kerberos encryption types = legacy' would force
                    rc4-hmac as a client even if the server supports
                    aes128-cts-hmac-sha1-96 and/or aes256-cts-hmac-sha1-96
                    (Samba#13135, Samba#15219, Samba#15237).

  + CVE-2022-37967: A service account with the special constrained
                    delegation permission could forge a more powerful
                    ticket than the one it was presented with (Samba#15231).
                     https://www.samba.org/samba/security/CVE-2022-37967.html

  + CVE-2022-38023: The "RC4" protection of the NetLogon Secure channel uses the
                    same algorithms as rc4-hmac cryptography in Kerberos,
                    and so must also be assumed to be weak (Samba#15240).
