FreeBSD : samba -- incorrect permission checks vulnerability (0fa15e08-92ec-11e1-a94a-00215c6a37bb)

This script is Copyright (C) 2012-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The Samba project reports :

Samba versions 3.4.x to 3.6.4 inclusive are affected by a
vulnerability that allows arbitrary users to modify privileges on a
file server.

Security checks were incorrectly applied to the Local Security
Authority (LSA) remote proceedure calls (RPC) CreateAccount,
OpenAccount, AddAccountRights and RemoveAccountRights allowing any
authenticated user to modify the privileges database.

This is a serious error, as it means that authenticated users can
connect to the LSA and grant themselves the 'take ownership'
privilege. This privilege is used by the smbd file server to grant the
ability to change ownership of a file or directory which means users
could take ownership of files or directories they do not own.
