If you use randomness (like in say CBC mode) that should suffice to give you IND-CPA security, no? And I believe GCM mode gives you IND-CCA2 security as well.
Actually CBC is a great mode for demonstrating how constructions built on secure primitives can introduce vulnerabilities. We can prepend a specific block to one with known plaintext in CBC mode to end up with garbage + plaintext we control.
