Descriptions

ext/standard/var.c in PHP 5.x through 7.1.24 on Windows allows attackers to cause a denial of service (NULL pointer dereference and application crash) because com and com_safearray_proxy return NULL in com_properties_get in ext/com_dotnet/com_handlers.c, as demonstrated by a serialize call on COM("WScript.Shell").

ext/standard/var.c en PHP 5.x hasta la versión 7.1.24 en Windows permite que los atacantes provoquen una denegación de servicio (desreferencia de puntero NULL y cierre inesperado de la aplicación) debido a que com y com_safearray_proxy devuelven NULL en com_properties_get en ext/com_dotnet/com_handlers.c, tal y como queda demostrado con una llamada serialize en COM("WScript.Shell").
