Description Kurt Seifried 2013-09-04 12:24:39 EDT
Thierry Carrez reports:

Title: Token revocation failure using Keystone memcache/KVS backends
Reporter: Kieran Spear (University of Melbourne)
Products: Keystone
Affects: Folsom, Grizzly

Kieran Spear from the University of Melbourne reported a vulnerability
in Keystone memcache and KVS token backends. The PKI token revocation
lists stored the entire token instead of the token ID, triggering
comparison failures, ultimately resulting in revoked PKI tokens still
being considered valid. Only Folsom and Grizzly Keystone setups making
use of PKI tokens with the memcache or KVS token backends are affected.
Havana setups, setups using UUID tokens, or setups using PKI tokens with
the SQL token backend are all unaffected.
