Descriptions
The pyGrub boot loader in Xen 3.0.3, 3.3.0, and Xen-3.3.1 does not support the password option in grub.conf for para-virtualized guests, which allows attackers with access to the para-virtualized guest console to boot the guest or modify the guest's kernel boot parameters without providing the expected password.
El pyGrub en Xen v3.0.3, v3.3.0, y Xen-3.3.1 no soporta la opción password en grub.conf para las invitaciones "para-virtualized", lo que permite a atacantes con acceso a la consola invitada para-virtualized iniciar la invitación o modificar los parámetros de arranque del kernel del invitado sin proporcionar el password esperado.
