Original advisory details:

 Michael Hanselmann discovered that the Samba client code incorrectly
 handled path separators. If a user were tricked into connecting to a
 malicious server, a remote attacker could use this issue to cause the
 client to access local pathnames instead of network pathnames.
 (CVE-2019-10218)

 Adam Xu discovered that Samba incorrectly handled the dirsync LDAP control.
 A remote attacker with 'get changes' permissions could possibly use this
 issue to cause Samba to crash, resulting in a denial of service. This issue
 only affected Ubuntu 14.04 ESM. (CVE-2019-14847)");
