+                   Release Notes for Samba 4.18.9
+                         November 29, 2023
+                   ==============================
+
+
+This is the latest stable release of the Samba 4.18 release series.
+It contains the security-relevant bugfix CVE-2018-14628:
+
+    Wrong ntSecurityDescriptor values for "CN=Deleted Objects"
+    allow read of object tombstones over LDAP
+    (Administrator action required!)
+    https://www.samba.org/samba/security/CVE-2018-14628.html
+
+
+Description of CVE-2018-14628
+-----------------------------
+
+All versions of Samba from 4.0.0 onwards are vulnerable to an
+information leak (compared with the established behaviour of
+Microsoft's Active Directory) when Samba is an Active Directory Domain
+Controller.
+
+When a domain was provisioned with an unpatched Samba version,
+the ntSecurityDescriptor is simply inherited from Domain/Partition-HEAD-Object
+instead of being very strict (as on a Windows provisioned domain).
+
+This means also non privileged users can use the
+LDAP_SERVER_SHOW_DELETED_OID control in order to view,
+the names and preserved attributes of deleted objects.
+
+No information that was hidden before the deletion is visible, but in
+with the correct ntSecurityDescriptor value in place the whole object
+is also not visible without administrative rights.
+
+There is no further vulnerability associated with this error, merely an
+information disclosure.
+
+Action required in order to resolve CVE-2018-14628!
+---------------------------------------------------
+
+The patched Samba does NOT protect existing domains!
+
+The administrator needs to run the following command
+(on only one domain controller)
+in order to apply the protection to an existing domain:
+
+  samba-tool dbcheck --cross-ncs --attrs=nTSecurityDescriptor --fix
+
+The above requires manual interaction in order to review the
+changes before they are applied. Typicall question look like this:
+
+  Reset nTSecurityDescriptor on CN=Deleted Objects,DC=samba,DC=org back to provision default?
+        Owner mismatch: SY (in ref) DA(in current)
+        Group mismatch: SY (in ref) DA(in current)
+        Part dacl is different between reference and current here is the detail:
+                (A;;LCRPLORC;;;AU) ACE is not present in the reference
+                (A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;SY) ACE is not present in the reference
+                (A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;DA) ACE is not present in the reference
+                (A;;CCDCLCSWRPWPSDRCWDWO;;;SY) ACE is not present in the current
+                (A;;LCRP;;;BA) ACE is not present in the current
+   [y/N/all/none] y
+  Fixed attribute 'nTSecurityDescriptor' of 'CN=Deleted Objects,DC=samba,DC=org'
+
+The change should be confirmed with 'y' for all objects starting with
+'CN=Deleted Objects'.
