evp_cipher_init_internal() takes a params array argument and this is processed late in the initialisation process for some ciphers (AEAD ones). This means that changing the IV length as a parameter will either truncate the IV (very bad if SP 800-38d section 8.2.1 is used) or grab extra uninitialised bytes. Truncation is very bad if SP 800-38d section 8.2.1 is being used to contruct a deterministic IV. This leads to an instant loss of confidentiality. Grabbing extra bytes isn't so serious, it will most likely result in a bad decryption. Problem reported by Tony Battersby of Cybernetics.com but earlier discovered and raised as issue #19822.
