CVE-2016-7129

Estado: ModificadaCrítica (9.8)—

La función php_wddx_process_data en 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 (error de segmentación) o tener otro posible impacto no especificado a través de un valor de tiempo ISO 8601 no válido, según lo demostrado mediante una llamada wddx_deserialize que no maneja adecuadamente un elemento dateTime en un documento XML wddxPacket.
