Bug#113732: not paranoid enough about device name

[Marcus Brinkmann]

Package: gnumach

gnumach device_open is not paranoid enough about the device name.  I haven't
tried it, but I think that having 128 non-digits with no trailing zero will
make gnumach run past the buffer in dev_name_lookup.

Maybe not worth fixing for gnumach (esp as opening a device requires the
device master port anyway).  But it reminds me of the broader issue of the
necessity to audit the code, esp at the borders caused by user supplied
data.

Thanks,
Marcus
