MediumCVSS 5.9
OpenStack Nova before 2012.1 allows someone with access to an EC2_ACCESS_KEY (equivalent to a username) to obtain the EC2_SECRET_KEY (equivalent to a password). Exposing the EC2_ACCESS_KEY via http or tools that allow man-in-the-middle over https could allow an attacker to easily...

HighCVSS 8.6
Versions of nova before 2012.1 could expose hypervisor host files to a guest operating system when processing a maliciously constructed qcow filesystem.
-
HighCVSS 7.5
An issue was discovered in OpenStack Nova 15.x through 15.1.0 and 16.x through 16.1.1. By detaching and reattaching an encrypted volume, an attacker may access the underlying raw volume and corrupt the LUKS header, resulting in a denial of service attack on the compute host. (The...

CVE-2017-17051 OpenStack Nova DoS by rebuilding the same instance with a new image multiple times
PublishedHighCVSS 8.6An issue was discovered in the default FilterScheduler in OpenStack Nova 16.0.3. By repeatedly rebuilding an instance with new images, an authenticated user may consume untracked resources on a hypervisor host leading to a denial of service, aka doubled resource allocations. This...
