Rack is vulnerable to a memory-exhaustion DoS through unbounded URL-encoded body parsing

Summary Rack::RequestPOST reads the entire request body into memory for Content-Type: application/x-www-form-urlencoded, calling rack.input.readnil without enforcing a length or cap. Large request bodies can therefore be buffered completely into process memory before parsing, leading to denial of...
