OpenStack Keystone 2012.1.3 does not invalidate existing tokens when granting or revoking roles, which allows remote authenticated users to retain the privileges of the revoked roles.

OpenStack Keystone before 2012.1.1, as used in OpenStack Folsom before Folsom-1 and OpenStack Essex, does not properly implement token expiration, which allows remote authenticated users to bypass intended authorization restrictions by (1) creating new tokens through token chaining, (2) leveraging possession of a token for a disabled user account, or (3) leveraging possession of a token for an account with a changed password.

Multiple SQL injection vulnerabilities in Keystone Digital Library Suite (DLS) 1.5.4 and earlier allow remote attackers to execute arbitrary SQL commands via the subject_type_id parameter in (1) the index page and (2) the search module.
