Inserting random garbage has always been a viable attack against Frost.
All you have to do is set an appropriate maximum data size.

How does that differ to just setting max size = 32kB in Frost? Sure you
have the code=28 issues, but so what? You can handle them - if you get a
code 28, there's a possibility that it's an attack, so you don't retry
it quite so aggressively.
