USN-1851-1: python-keystoneclient vulnerability
Ubuntu Security Notice USN-1851-1
3rd June, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.04
The python client library for Keystone did not properly verify expired PKI tokens.
- python-keystoneclient - Client library for OpenStack Identity API
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
The problem can be corrected by updating your system to the following package version:
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.
