Ubuntu Security Notice USN-1851-1

3rd June, 2013

python-keystoneclient vulnerability

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.

Software description

  • 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
than intended.
