How to fix?

NVD Description

Note: Versions mentioned in the description apply only to the upstream samba4-test package and not the samba4-test package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

The owner_set function in smbcacls.c in smbcacls in Samba 4.0.x before 4.0.16 and 4.1.x before 4.1.6 removes an ACL during use of a --chown or --chgrp option, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging an unintended administrative change.
