  <impact type="normal">
    <p>A remote attacker could entice a user to process an XML file using a
      specially crafted XSLT stylesheet in an application linked against
      libxslt, possibly resulting in a Denial of Service condition.

    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All libxslt users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-libs/libxslt-1.1.26-r3"
