  perform expiry checks for the PKI tokens used in Keystone. If Keystone were
  setup to use PKI tokens, a previously authenticated user could continue to
  use a PKI token for longer than intended. This issue only affected Ubuntu
  12.10 which does not use PKI tokens by default. (CVE-2013-2104)

  Jose Castro Leon discovered that Keystone did not properly authenticate
  users when using the LDAP backend. An attacker could obtain valid tokens
  and impersonate other users by supplying an empty password. By default,
  Ubuntu does not use the LDAP backend. (CVE-2013-2157)";
