title: 'Nova host data leak through resize/migration'
description: 'Matthew Booth from Red Hat reported a vulnerability in Nova instance
resize/migration. By overwriting an ephemeral or root disk with a malicious
image before requesting a resize, an authenticated user may be able to read
arbitrary files from the compute host. Only setups using libvirt driver with
raw storage and setting "use_cow_images = False" (not default) are affected.'
errata: 'The former fix did not take into account the usage of non-disk-image
backends and caused a regression for this use-case. This update provides an
additional fix for that issue. Moreover, the kilo backport caused a regression
in live migration where the disk info file is JSON encoded. This second update
provides an additional fix for stable/kilo.'
