Unbounded p2c headers may be used to cause an application that accept PBES algorithms to spend alot of resources running PBKDF2 with a very high number of iterations. Clamp the default maximum to 16384 (double the default of 8192). An application that wants to use more iterations will have to chenge the jwa default max.
