Details

It was discovered that Samba did not automatically replicate ACLs set to
inherit down a subtree on AD Directory, contrary to expectations. This
issue was only addressed in Ubuntu 18.04 LTS, Ubuntu 19.04 and Ubuntu
19.10. (CVE-2019-14902)

Robert Święcki discovered that Samba incorrectly handled certain character
conversions when the log level is set to 3 or above. In certain
environments, a remote attacker could possibly use this issue to cause
Samba to crash, resulting in a denial of service. (CVE-2019-14907)

Christian Naumer discovered that Samba incorrectly handled DNS zone
scavenging. This issue could possibly result in some incorrect data being
written to the DB. This issue only applied to Ubuntu 19.04 and Ubuntu
19.10. (CVE-2019-19344)
