FreeBSD : samba -- nss_info plugin privilege escalation vulnerability (2bc96f18-683f-11dc-82b6-02e0185f8d72)

This script is Copyright (C) 2007-2015 Tenable Network Security, Inc.

Synopsis :

The remote FreeBSD host is missing one or more security-related

Description :

The Samba development team reports :

The library provides an nss_info extension to Winbind for
retrieving a user's home directory path, login shell and primary group
id from an Active Directory domain controller. This functionality is
enabled by defining the 'winbind nss info' smb.conf option to either
'sfu' or 'rfc2307'.

Both the Windows 'Identity Management for Unix' and 'Services for
Unix' MMC plug-ins allow a user to be assigned a primary group for
Unix clients that differs from the user's Windows primary group. When
the rfc2307 or sfu nss_info plugin has been enabled, in the absence of
either the RFC2307 or SFU primary group attribute, Winbind will assign
a primary group ID of 0 to the domain user queried using the
getpwnam() C library call.
