    <p>A heap-based buffer overflow in gThumb’s

    <p>A remote attacker could entice a user to open a specially crafted image
      file using gThumb, possibly resulting in execution of arbitrary code with
      the privileges of the process or a Denial of Service condition.

  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All gThumb users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=media-gfx/gthumb-3.10.0"
    </code>
