Descriptions

An information leak vulnerability was found in Undertow. If all headers are not written out in the first write() call then the code that handles flushing the buffer will always write out the full contents of the writevBuffer buffer, which may contain data from previous requests.

Si no están escritas todas las cabeceras en la primera llamada write(), el código que maneja las escrituras al búfer siempre escribirá el contenido completo del búfer writevBuffer, que podría contener datos de peticiones anteriores.
