sync between domain controllers (CVE-2019-14902).

When processing untrusted string input Samba can read past the end of
the allocated buffer when printing a 'Conversion error' message to the
logs. This can cause a crash after the failed character conversion when
operating at log level 3 or above (CVE-2019-14907).

During DNS zone scavenging (of expired dynamic entries) in a Samba AD
DC, there is a read of memory after it has been freed (CVE-2019-19344).

Note that manual intervention is required to fully implement the fix
for CVE-2019-14902. See the upstream advisory for details.");
