Descriptions

In all versions of PHP 7, during the unserialization process, resizing the 'properties' hash table of a serialized object may lead to use-after-free. A remote attacker may exploit this bug to gain arbitrary code execution.

En todas las versiones de PHP 7, durante el proceso no serializado, redimensionando las "propiedades" de la tabla hash de un objeto serializado puede conducir a un uso después de liberación de memoria. Un atacante remoto puede explotar este error para obtener ejecución de código arbitraria.
