## Overview

OpenStack Compute (nova) 2015.1 through 2015.1.1, 2014.2.3, and earlier does not stop the migration process when the instance is deleted, which allows remote authenticated users to cause a denial of service (disk, network, and other resource consumption) by resizing and then deleting an instance.

## Affected packages

- `nova < 112.0.0.0b3`

## Remediation

Upgrade to a patched release:

- `nova 112.0.0.0b3`
