There is this small web application, which is reachable under Pointer.rodeo, and it provides a single service at the moment. It will generate a pattern to aid you in buffer overflow exploitation.
For example you can make a request with
curl and pipe it directly into your
targeted application. If you see your favorite register overwritten by parts of
the pattern, you can than ask Pointer.rodeo again to
calculate the buffer size for you.
If you want more examples on how to use the service, head of to Pointer.rodeo.
