Descriptions
conduit-hyper integrates a conduit application with the hyper server. Prior to version 0.4.2, `conduit-hyper` did not check any limit on a request's length before calling [`hyper::body::to_bytes`](https://docs.rs/hyper/latest/hyper/body/fn.to_bytes.html). An attacker could send a malicious request with an abnormally large `Content-Length`, which could lead to a panic if memory allocation failed for that request. In version 0.4.2, `conduit-hyper` sets an internal limit of 128 MiB per request, otherwise returning status 400 ("Bad Request"). This crate is part of the implementation of Rust's [crates.io](https://crates.io/), but that service is not affected due to its existing cloud infrastructure, which already drops such malicious requests. Even with the new limit in place, `conduit-hyper` is not recommended for production use, nor to directly serve the public Internet.
conduit-hyper integra una aplicación de conducto con el hiperservidor. Antes de la versión 0.4.2, `conduit-hyper` no verificaba ningún límite en la longitud de una solicitud antes de llamar a [`hyper::body::to_bytes`](https://docs.rs/hyper/latest/hyper/body /fn.to_bytes.html). Un atacante podría enviar una solicitud maliciosa con una ""longitud de contenido"" anormalmente grande, lo que podría provocar pánico si fallara la asignación de memoria para esa solicitud. En la versión 0.4.2, `conduit-hyper` establece un límite interno de 128 MiB por solicitud; de lo contrario, devuelve el estado 400 (""Solicitud incorrecta""). Esta caja es parte de la implementación de [crates.io](https://crates.io/) de Rust, pero ese servicio no se ve afectado debido a su infraestructura de nube existente, que ya descarta este tipo de solicitudes maliciosas. Incluso con el nuevo límite establecido, ""conduit-hyper"" no se recomienda para uso en producción ni para servir directamente a la Internet pública.
