Synopsis
========

A vulnerability in NTFS-3G allows local users to gain root privileges.

Background
==========

NTFS-3G is a stable, full-featured, read-write NTFS driver for various
operating systems.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  sys-fs/ntfs3g              < 2016.2.22              >= 2016.2.22

Description
===========

NTFS-3G is affected by the same vulnerability as reported in "GLSA
201603-04" when the bundled fuse-lite implementation is used.

Impact
======

A local user could gain root privileges.

Workaround
==========

There is no known workaround at this time. However, on Gentoo when the
"external-fuse" USE flag is set or the "suid" USE flag is not set then
NTFS-3G is not affected. Both of these cases are the default
configuration.

Resolution
==========

All NTFS-3G users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=sys-fs/ntfs3g-2016.2.22"
