  <impact type="normal">
    <p>A remote attacker could entice a user to open a specially crafted ELF
      binary using gdb, possibly resulting in information disclosure or a
      Denial of Service condition.

    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All gdb users should upgrade to the latest version:</p>
