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.
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)
