No, you are completely missing the point.
Possible security issues in this decoder will only be
searched (and therefore found) if the decoder doesn't
timeout quickly on damaged files.
I assume this is the result of a (simple) cost-benefit-
analysis by the people running the fuzzing systems.
Nobody asks you to fix the issues, blocking them is an
interesting concept security-wise.
