CWE-264  (opens in a new tab)

How to fix?

Upgrade samba to version 4.0.16, 4.1.6 or higher.

Overview

Affected versions of this package are vulnerable to Access Restriction Bypass. 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.
