    <p>A remote attacker could entice a user to process a specially crafted
      string with functions like pango_itemize, possibly resulting in execution
      of arbitrary code with the privileges of the process or a Denial of
      Service condition.

  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All Pango users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=x11-libs/pango-1.42.4-r2"
    </code>
