Create an Unexpected Object in During WDDX Deserialization

In During WDDX Deserialization, an unexpected object can be created via the crafted wddx pockets, and bypass __wakeup() method

class obj {
	function __wakeup() {

$wddx = <<<EOT
<?xml version='1.0'?>
<wddxPacket version='1.0'>
			<var name='php_class_name'>
			<var name='prop'>

Like unserialize, wddx_deserialize() must not be fed with untrusted input.
Consequently we don't consider bugs in wddx_deserialize security vulnerabilities.
