Description :

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.

validate the project id. A remote authenticated attacker may be able
to use this to access other projects. (CVE-2014-3520)

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,
