CVE-2019-19344 kcc dns scavenging: Fix use after free in dns_tombstone_records_zone
ldb_msg_add_empty reallocates the underlying element array, leaving
old_el pointing to freed memory.
This patch takes two defensive copies of the ldb message, and performs
the updates on them rather than the ldb messages in the result.

CVE-2019-14907 lib/util: Do not print the failed to convert string into the logs
The string may be in another charset, or may be sensitive and
certainly may not be terminated. It is not safe to just print.
Found by Robert Święcki using a fuzzer he wrote for smbd.

CVE-2019-14902 dsdb: Change basis of descriptor module deferred processing to be GUIDs
We can not process on the basis of a DN, as the DN may have changed in a rename,
not only that this module can see, but also from repl_meta_data below.
Therefore remove all the complex tree-based change processing, leaving only
a tree-based sort of the possible objects to be changed, and a single
stopped_dn variable containing the DN to stop processing below (after
a no-op change).

+ ==============================
+ Release Notes for Samba 4.11.5
+ 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
+ above.
+o CVE-2019-19344: Use after free during DNS zone scavenging in Samba AD DC.
+
+
+=======
+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.
+
+
+Changes since 4.11.4:
+---------------------
+
+o Andrew Bartlett <abartlet at samba.org>
+ * BUG 12497: CVE-2019-14902: Replication of ACLs down subtree on AD Directory
+ not automatic.
+ * BUG 14208: CVE-2019-14907: lib/util: Do not print the failed to convert
+ string into the logs.
+
+o Gary Lockyer <gary at catalyst.net.nz>
+ * BUG 14050: CVE-2019-19344: kcc dns scavenging: Fix use after free in
+ dns_tombstone_records_zone.
