Descriptions
GNU GRand Unified Bootloader (GRUB) 2 1.97 only compares the submitted portion of a password with the actual password, which makes it easier for physically proximate attackers to conduct brute force attacks and bypass authentication by submitting a password whose length is 1.
GNU GRand Unified Bootloader (GRUB) 2 v1.97 únicamente compara el fragmento enviado de una contraseña con la contraseña actual, lo que facilita que atacantes próximos realicen ataques de fuerza bruta y eviten la autenticación mediante el envío de una contraseña de longitud 1.
