Bug description:
We found this problem in our Diablo code base - I think by inspection
its still valid in upstream as well but a bit harder to check as the
code has changed (BootFromVolumeController no longer exists, and os-
volume_boot now just inherits from the servers API).
Fillling anyway as its pretty serious, in the hope that someone can
verify or dismiss it.
Boot from volume allows a volume to be passed to the create method via
the block_device_mapping parameter. This parameter is not validated
as having to be a volume belonging to the user creating the instance,
so providing I know the valid ID of a volume belonging to another user
I can create VM and gain access to that volume (c.f volume attachment
which does make explicit checks for both the ownership and status of a
volume)
The volume ownership and status should be explicitly checked in the
compute.api layer
