## Overview

keystone/middleware/auth_token.py in OpenStack Nova Folsom, Grizzly, and Havana uses an insecure temporary directory for storing signing certificates, which allows local users to spoof servers by pre-creating this directory, which is reused by Nova, as demonstrated using /tmp/keystone-signing-nova on Fedora.

## Affected packages

- `python-keystoneclient < 0.2.4`

## Remediation

Upgrade to a patched release:

- `python-keystoneclient 0.2.4`
