  <affected>
    <package name="net-fs/nfs-utils" auto="yes" arch="*">

  <background>
    <p>
    nfs-utils contains the client and daemon implementations for the NFS
    protocol.
    </p>
  </background>
  <description>
    <p>
    Michele Marcionelli reported that nfs-utils invokes the hosts_ctl()
    function with the wrong order of arguments, which causes TCP Wrappers
    to ignore netgroups.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could bypass intended access restrictions, i.e. NFS
    netgroups, and gain access to restricted services.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All nfs-utils users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=net-fs/nfs-utils-1.1.3"</code>
