Proposed impact description:

Title: Expiration check failure in Keystone PKI tokens validation
Reporter: Eoghan Glynn (Red Hat)
Products/Affects: Keystone (Folsom only), python-keystoneclient (0.2.0+)

Description:
Eoghan Glynn from Red Hat reported a vulnerability in expiry checks for PKI tokens in the Keystone authentication middleware. Expired tokens for authenticated users could continue to be used as long as the user wasn't disabled, potentially resulting in the bypass of intended security policies. Only setups using PKI tokens are affected.

Note:
The affected code was added to Keystone in the Folsom release, but was moved to python-keystoneclient during the Grizzly development cycle.
