Solve the following python programming problem given the following code:
def CryptoJS_AES_decrypt(encrypted, password, key_length = 32) : 
    def derive_key_and_iv(password, salt, key_length, iv_length) : 
        d = d_i = '' 
        while (len (d) < (key_length + iv_length)) : 
            d_i = md5 (((d_i + password) + salt)).digest () 
            d += d_i 
return (d [: key_length], d [key_length : (key_length + iv_length)]) 
bs = 16 
    salt = encrypted [len ('Salted__') : bs] 
    (key, iv) = derive_key_and_iv (password, salt, key_length, bs) 
    cipher = AES_CBC (key = key, keySize = 32) 
    return cipher.decrypt (encrypted [bs :], key_length) 

    
    

    Fix the buggy line: return cipher.decrypt (encrypted [bs :], key_length)

#Here is Python code to fix the buggy line: return cipher.

return cipher.decrypt (encrypted [bs :], iv)
