+                   Release Notes for Samba 4.16.10

+                   ===============================
+
+
+This is a security release in order to address the following defects:
+
+o 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.
+                 https://www.samba.org/samba/security/CVE-2023-0922.html
+
+o 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.
