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...

Rack's multipart parser buffers unbounded per-part headers, enabling DoS (memory exhaustion)

Summary Rack::Multipart::Parser can accumulate unbounded data when a multipart part’s header block never terminates with the required blank line CRLFCRLF. The parser keeps appending incoming bytes to memory without a size cap, allowing a remote attacker to exhaust memory and cause a denial of...
