Descriptions
In PHP before 5.6.31, an invalid free in the WDDX deserialization of boolean parameters could be used by attackers able to inject XML for deserialization to crash the PHP interpreter, related to an invalid free for an empty boolean element in ext/wddx/wddx.c.
En PHP anterior a versión 5.6.31, una liberación no válida en la deserialización WDDX de parámetros booleanos podría ser utilizada por atacantes capaces de inyectar XML para la deserialización en el bloqueo del intérprete PHP, relacionado con una liberación no válida para un elemento booleano vacío en el archivo ext/wddx/wddx.c.
