title: 'Nova compute DoS through ephemeral disk backing files'
|
|
|
|
description: 'Phil Day from HP reported a vulnerability in the libvirt driver handling
|
|
of ephemeral disk backing files on Nova compute nodes. By repeatedly creating snapshots,
|
|
changing the os_type to a new random value, and spawning new instances from the
|
|
snapshot (and quickly deleting those instances), an authenticated user could generate
|
|
lots of different ephemeral disk backing files and fill up compute node disks, potentially
|
|
resulting in a Denial of Service against a Nova setup. Only Nova setups running
|
|
the libvirt driver are affected.'
