Security Fix(es):

* It was found that Samba always requested forwardable tickets when using
Kerberos authentication. A service to which Samba authenticated using
Kerberos could subsequently use the ticket to impersonate Samba to other
services or domain users. (CVE-2016-2125)

* A flaw was found in the way Samba handled PAC (Privilege Attribute
Certificate) checksums. A remote, authenticated attacker could use this
flaw to crash the winbindd process. (CVE-2016-2126)

* A race condition was found in samba server. A malicious samba client
could use this flaw to access files and directories, in areas of the
server file system not exported under the share definitions.
(CVE-2017-2619)
