Radamsa is a cool tool that combines a set of fuzzers which generate data based on input string. You can feed it a PDF file for example and Radamsa will produce a bunch of PDF-alike documents that are fuzzed in all imaginable forms. Just see this:
$ echo "test123" | radamsa -n 10
ttestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestestest1

Perfect for looking for all kinds of buffer overflows. And this tool can be especially useful combined with Burp Suite, that is why here is quick and dirty extension that enables you to use Radamsa to generate Burp Suite’s Intruder payloads:
