Descriptions

Netty project is an event-driven asynchronous network application framework. Starting in version 4.1.83.Final and prior to 4.1.86.Final, when calling `DefaultHttpHeadesr.set` with an _iterator_ of values, header value validation was not performed, allowing malicious header values in the iterator to perform HTTP Response Splitting. This issue has been patched in version 4.1.86.Final. Integrators can work around the issue by changing the `DefaultHttpHeaders.set(CharSequence, Iterator<?>)` call, into a `remove()` call, and call `add()` in a loop over the iterator of values.

El proyecto Netty es un framework de aplicación de red asíncrona impulsado por eventos. A partir de la versión 4.1.83.Final y anteriores a la 4.1.86.Final, al llamar a `DefaultHttpHeadesr.set` con un _iterator_ de valores, no se realizaba la validación del valor del encabezado, lo que permitía que los valores de encabezado maliciosos en el iterador realizaran la división de respuesta HTTP. Este problema se solucionó en la versión 4.1.86.Final. Los integradores pueden solucionar el problema cambiando la llamada `DefaultHttpHeaders.set(CharSequence, Iterator)` a una llamada `remove()` y llamando a `add()` en un bucle sobre el iterador de valores.
