Moving this discussion here as it makes little to non sense to discuss
that any longer on security@

We are now very late behind an acceptable delay to provide a fix for
the hash DoS, to say it nicely.

I'd strongly suggest to release 5.3.9 (RC5 has been tested now) final
this week using the max_input_vars fix, with the modification from
Laruence (but with a larger limit). Laruence addition also fixes
serialize or json, which are parts that need this fix as well as it is
impossible to valid a string manually (length check only is not enough
or cannot work in all cases).

But 1st of all, the fix addition has to be applied and fully tested.
But if the addition is not desired yet, then we must at least release
5.3.9 with Dmitry's fix only and we can fix json&serialize later,
ideally within 2 weeks max.
