title: Raw underlying encrypted volume access
|
||||||
|
|
||||||
|
description: >
|
||||||
|
Lee Yarwood (Red Hat) reported a vulnerability in Nova encrypted
|
||||||
|
volumes handling. By detaching and reattaching an encrypted volume
|
||||||
|
an attacker may access the underlying raw volume and corrupt the
|
||||||
|
LUKS header resuling in a denial of service attack on the compute host.
|
||||||
|
All Nova setups supporting encrypted volumes are affected.
