USN-1851-1: python-keystoneclient vulnerability

3 June 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

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

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