During this process, with a line big enough it's possible to make this variable to overflow leading to a out-of-bounds write in the heap based buffer. This flaw may be leveraged to corrupt grub's internal critical data and secure boot bypass is not discarded as consequence."},{"lang":"es","value":" El comando read se utiliza para leer la entrada del teclado del usuario, mientras que reads mantiene la longitud de la entrada en un valor entero de 32 bits que se utiliza para reasignar el búfer de línea para aceptar el siguiente carácter.
