Ubuntu Security Notice USN-1851-1
June 03, 2013

python-keystoneclient vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.04

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.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.04:
python-keystoneclient 1:0.2.3-0ubuntu2.2

In general, a standard system update will make all the necessary changes.
