  <background>
    <p>
    The PEAR XML-RPC and phpxmlrpc libraries are both PHP
    implementations of the XML-RPC protocol.
    </p>
  </background>
  <description>
    <p>
    Stefan Esser of the Hardened-PHP Project discovered that the PEAR
    XML-RPC and phpxmlrpc libraries were improperly handling XMLRPC
    requests and responses with malformed nested tags.
    </p>
  </description>
  <impact type="high">
    <p>
    A remote attacker could exploit this vulnerability to inject
    arbitrary PHP script code into eval() statements by sending a specially
    crafted XML document to web applications making use of these libraries.
    </p>
  </impact>
  <workaround>
    <p>
    There are no known workarounds at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All PEAR-XML_RPC users should upgrade to the latest available
    version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-php/PEAR-XML_RPC-1.4.0&quot;</code>
    <p>
    All phpxmlrpc users should upgrade to the latest available
    version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-php/phpxmlrpc-1.2-r1&quot;</code>
