Descriptions

ext/spl/spl_array.c in PHP before 5.6.26 and 7.x before 7.0.11 proceeds with SplArray unserialization without validating a return value and data type, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data.

ext/spl/spl_array.c en PHP en versiones anteriores a 5.6.26 y 7.x en versiones anteriores a 7.0.11 procede con SplArray no serializado sin validar un valor de retorno y tipo de dato, lo que permite a atacantes remotos provocar una denegación de servicio o tener otro posible impacto no especificado a través de datos serializados manipulados.
