The V3 API in OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before Juno-3 updates the issued_at 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/.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The V3 API in OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before Juno-3 updates the

    (CVE-2014-3476)

    Jamie Lennox discovered that OpenStack Keystone did not properly validate the project id. A remote     authenticated attacker may be able to use this to access other projects. (CVE-2014-3520)

    Brant Knudson and Lance Bragstad discovered that OpenStack Keystone would not always revoke tokens     correctly. If Keystone were configured to use revocation events, a remote authenticated attacker could     continue to have access to resources. (CVE-2014-5251, CVE-2014-5252, CVE-2014-5253)
