Samba 'CAP_DAC_OVERRIDE' File Permission Security Bypass

This script is Copyright (C) 2010-2016 Tenable Network Security, Inc.

Synopsis :

The remote file server is vulnerable to a security bypass attack.

Description :

The remote Samba server has a flaw that causes all smbd processes,
when libcap support is enabled, to inherit 'CAP_DAC_OVERRIDE'
capabilities, which in turn causes all file system access to be
allowed even when permissions should have been denied.

A remote, authenticated attacker can exploit this flaw to gain access
to sensitive information on Samba shares that are accessible to their
user id.

Solution :

Risk factor :
