openstack-keystone: token expiration date stored incorrectly

A flaw was found in keystone revocation events that resulted in the "issuedat" time being updated when a token created by the V2 API was processed by the V3 API. This could allow a user to evade token revocation. Only OpenStack Identity setups configured to make use of revocation events and UUID...

PYSEC-2014-108

The V3 API in OpenStack Identity Keystone 2014.1.x before 2014.1.2.1 and Juno before Juno-3 updates the issuedat value for UUID v2 tokens, which allows remote authenticated users to bypass the token expiration and retain access via a verification 1 GET or 2 HEAD request to v3/auth/tokens/...
