CVE-2018-16853

Priority
Description
Samba from version 4.7.0 has a vulnerability that allows a user in a Samba
AD domain to crash the KDC when Samba is built in the non-default MIT
Kerberos configuration. With this advisory the Samba Team clarify that the
MIT Kerberos build of the Samba AD DC is considered experimental. Therefore
the Samba Team will not issue security patches for this configuration.
Additionally, Samba 4.7.12, 4.8.7 and 4.9.3 have been issued as security
releases to prevent building of the AD DC with MIT Kerberos unless
--with-experimental-mit-ad-dc is specified to the configure command.
Notes
mdeslaurUbuntu package is not built with MIT Kerberos
