  <impact type="normal">
    <p>
    A remote attacker can entice a user to open specially crafted "man:" or
    "ghelp:" URIs in yelp, or an application using yelp such as Firefox or
    Evolution, and execute arbitrary code with the privileges of that user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All yelp users running GNOME 2.22 should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=gnome-extra/yelp-2.22.1-r2&quot;</code>
    <p>
    All yelp users running GNOME 2.20 should upgrade to the latest version:
