"value" : "A buffer overflow was found in grub_font_construct_glyph(). A malicious crafted pf2 font can lead to an overflow when calculating the max_glyph_size value, allocating a smaller than needed buffer for the glyph, this further leads to a buffer overflow and a heap based out-of-bounds write. An attacker may use this vulnerability to circumvent the secure boot mechanism."

"value" : "Se encontr\u00f3 un desbordamiento del b\u00fafer en grub_font_construct_glyph(). Una fuente pf2 manipulada maliciosamente puede provocar un desbordamiento al calcular el valor max_glyph_size, asignando un b\u00fafer m\u00e1s peque\u00f1o de lo necesario para el glifo, lo que adem\u00e1s provoca un desbordamiento del b\u00fafer y una escritura fuera de los l\u00edmites basada en el heap. Un atacante puede utilizar esta vulnerabilidad para eludir el mecanismo de arranque seguro."
