The MySQL token driver in OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before Juno-3 stores timestamps with the incorrect precision, which causes the expiration comparison for tokens to fail and allows remote authenticated users to retain access via an expired token.

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

  - The MySQL token driver in OpenStack Identity (Keystone) 2014.1.x before 2014.1.2.1 and Juno before Juno-3
    stores timestamps with the incorrect precision, which causes the expiration comparison for tokens to fail
    and allows remote authenticated users to retain access via an expired token. (CVE-2014-5251)

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2324-1 advisory.

    Steven Hardy discovered that OpenStack Keystone did not properly handle chained delegation. A remove     authenticated attacker could use this to gain privileges by creating a new token with additional roles.
    (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)
