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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
