      Here's what new in &xslt4j-current;.

    <s3 title="Fix for CVE-2014-0107 insufficient secure processing">
      <p>
        When using FEATURE_SECURE_PROCESSING ("http://javax.xml.XMLConstants/feature/secure-processing") on a TransformerFactory, the output properties:
      </p>
      <ul>
        <li>{http://xml.apache.org/xalan}content-handler</li>
        <li>{http://xml.apache.org/xalan}entities</li>
        <li>{http://xml.apache.org/xslt}content-handler</li>
        <li>{http://xml.apache.org/xslt}entities</li>
      </ul>
      <p>
        should be ignored (see http://xml.apache.org/xalan-j/usagepatterns.html#outputprops)
      </p>
      <p>
        These properties can be used to load an arbitrary class or access an arbitrary URL/resource so are problematic when secure processing is desired.
      </p>
      <p>      
        <code>  
          &lt;xsl:output xalan:content-handler="org.example.BadClass" ...
        </code>   
      </p>
      <p>      
        <code>  
          &lt;xsl:output xalan:entities="http://example.org/reallyLargeFile.bin" ...
        </code>   
      </p>
      <p>
        These features could be used to load a class that had undesirable side-effects or to load a large file and exhaust memory, etc. 
      </p>
