Ubuntu Security Advisory USN-1852-2 covers a flaw in python-novaclient, urging immediate system updates for users.
The python client library for Keystone did not properly verify expired PKI tokens.

Summary

The python client library for Keystone did not properly verify expired PKI

tokens.

Software Description:

- python-keystoneclient: Client library for OpenStack Identity API

Details:

Eoghan Glynn and Alex Meade discovered that python-keystoneclient did not

properly perform expiry checks for the PKI tokens used in Keystone. If

Keystone were setup to use PKI tokens (the default in Ubuntu 13.04), a

previously authenticated user could continue to use a PKI token for longer

than intended.
