Samba 'CAP_DAC_OVERRIDE' File Permission Security Bypass (version check)

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 is potentially affected by a security bypass
vulnerability because of 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 may be able to exploit this flaw to
gain access to sensitive information on Samba shares that are
accessible to their user id.

Solution :

Risk factor :

High / CVSS Base Score : 8.5
