This one is getting better and better :) New version:

Title: Missing expiration check 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, potentially resulting in the bypass of intended security policies. The effect of PKI token revocation is also reversed when the token expires, in the sense that a revoked token is once again treated as being valid. 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.
