Subject: CVE Request -- Xen -- PyGrub

Hello Steve, vendors,

   Xen's PyGrub, when grub.conf was configured with password protection,
did not check for the password at host boot time. An attacker, with physical
access to the host, could use this flaw to change the OS booting configuration.

Upstream patches:

Affected Xen versions:
Issue confirmed in Xen-3.0.3, Xen-3.3.0 and Xen-3.3.1.

----------- (PoC)

Could you please allocate a new CVE id?

Thanks && Regards, Jan.
