Descriptions

The php_wddx_pop_element function in 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 base64 binary value, as demonstrated by a wddx_deserialize call that mishandles a binary element in a wddxPacket XML document.

La función php_wddx_pop_element 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 (referencia a puntero NULL y caída de aplicación) o tener otro posible impacto no especificado a través de un valor binario base64 no válido, según lo demostrado mediante una llamada wddx_deserialize que no maneja adecuadamente un elemento binario en un documento XML wddxPacket.
