Descriptions

ext/wddx/wddx.c in PHP before 5.6.25 and 7.x before 7.0.10 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) or possibly have unspecified other impact via an invalid wddxPacket XML document that is mishandled in a wddx_deserialize call, as demonstrated by a stray element inside a boolean element, leading to incorrect pop processing.

ext/wddx/wddx.c en PHP en versiones anteriores a 5.6.25 y 7.x en versiones anteriores a 7.0.10 permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL y caída de aplicación) o tener otro posible impacto no especificado a través de un documento XML wddxPacket no válido que es manejado incorrectamente en una llamada wddx_deserialize, según lo demostrado mediante un elemento stray dentro de un elemento booleano, que conduce a un procesamiento pop incorrecto.
