As consequence an attacker can craft an input which will lead to a out-of-bounds write into grub2's heap, leading to memory corruption and availability issues. Although complex, arbitrary code execution could not be discarded."},{"lang":"es","value":"Al representar ciertas secuencias Unicode, el código de fuente de grub2 no se valida correctamente si el ancho y alto del glifo informado están restringidos dentro del tamaño del mapa de bits. Como consecuencia, un atacante puede crear una entrada que provocará una escritura fuera de los límites en el montón de grub2, lo que provocará daños en la memoria y problemas de disponibilidad.
