                   Release Notes for Samba 4.9.18
                           January 21, 2020

This is a security release in order to address the following defects:

o CVE-2019-14902: Replication of ACLs set to inherit down a subtree on AD
		  Directory not automatic.        
o CVE-2019-14907: Crash after failed character conversion at log level 3 or
o CVE-2019-19344: Use after free during DNS zone scavenging in Samba AD DC.
o  CVE-2019-14902:                                                                                
   The implementation of ACL inheritance in the Samba AD DC was not complete,
   and so absent a 'full-sync' replication, ACLs could get out of sync between
   domain controllers. 

o  CVE-2019-14907:
   When processing untrusted string input Samba can read past the end of the
   allocated buffer when printing a "Conversion error" message to the logs.

o  CVE-2019-19344:                                                                                
   During DNS zone scavenging (of expired dynamic entries) there is a read of
   memory after it has been freed.

For more details and workarounds, please refer to the security advisories.
