    <p>
    Paul Szabo reported an insufficient input sanitization when processing
    Device Control Request Status String (DECRQSS) sequences.
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to display a file containing
    specially crafted DECRQSS sequences, possibly resulting in the remote
    execution of arbitrary commands with the privileges of the user viewing
    the file.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All xterm users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=x11-terms/xterm-239&quot;</code>
  </resolution>
