  <background>
    <p>NTFS-3G is a stable, full-featured, read-write NTFS driver for various
      operating systems.
    </p>
  </background>
  <description>
    <p>The NTFS-3G driver does not properly clear environment variables before
      invoking mount or umount.
    </p>
    
    <p>This flaw is similar to the vulnerability described in
      “GLSA-201701-19” and “GLSA-201603-04” referenced below but is now
      implemented in the NTFS-3G driver itself.
    </p>
  </description>
  <impact type="normal">
    <p>A local user could gain root privileges.</p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time. However, on Gentoo when the
      “suid” USE flag is not set (which is the default) an attacker cannot
      exploit the flaw.
    </p>
  </workaround>
  <resolution>
    <p>All NTFS-3G users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sys-fs/ntfs3g-2016.2.22-r2"
    </code>
