To: "The development of GNU GRUB" No I meant full access to just obe of guest partitions. E.g. FTP may be using separate partition and non-admins may have control over it. If system has some kind of automatic user creation and /home is separate someone may register as boot or grub and put grub.xen in his directory. If /tmp is on separate partition and not in RAM then everybody can put grub.xen to /tmp/grub/grub.xen On Dec 12, 2013 5:39 PM, "Colin Watson" wrote: > On Thu, Dec 12, 2013 at 05:24:50PM +0100, Vladimir 'phcoder' Serbinenko > wrote: > > This config has a security problem.
