Thanks for the detailed response! That's interesting. I didn't know that a system was considered broken if, knowing plaintext (and breaking a hash function) allows an attacker to rewrite a message. Probably pretty basic stuff to you.

Different kinds of attacks often play off each other, so that a small amount of known plaintext allows you to modify the decrypted plaintext of a message in ways that will reveal more plaintext. So, for instance, a CBC padding oracle is an attack that allows you to decrypt messages byte-by-byte --- but it's stopped entirely by a proper MAC on the message.
