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.

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