Vulnerability Insight: CVE-2015-6831 Use after free vulnerability was found in unserialize() function. We can create ZVAL and free it via Serializable::unserialize.

CVE-2015-6836 A type confusion occurs within SOAP serialize_function_call due to an insufficient validation of the headers field. In the SoapClient's __call method, the verify_soap_headers_array check is applied only to headers retrieved from zend_parse_parameters, problem is that a few lines later, soap_headers could be updated or even replaced with values from the __default_headers object fields.
