    <p>
    Multiple integer overflow and signedness errors have been reported in
    the excel_read_HLINK() function in file plugins/excel/ms-excel-read.c
    when processing XLS HLINK opcodes.

  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted XLS
    file, possibly resulting in the remote execution of arbitrary code with
    the privileges of the user running the application.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Gnumeric users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose "&gt;=app-office/gnumeric-1.8.1"</code>
