Details
=======

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.
