In affected versions `sendOverloadError` is going to assume the active request exists when `envoy.load_shed_points.http1_server_abort_dispatch` is configured. If `active_request` is nullptr, only onMessageBeginImpl() is called. However, the `onMessageBeginImpl` will directly return ok status if the stream is already reset leading to the nullptr reference. The downstream reset can actually happen during the H/2 upstream reset. As a result envoy may crash. This issue has been addressed in releases 1.32.3, 1.31.5, 1.30.9, and 1.29.12. Users are advised to upgrade. Users unable to upgrade may disable `http1_server_abort_dispatch` load shed point and/or use a high threshold."

En las versiones afectadas, `sendOverloadError` asumir\u00e1 que existe la solicitud activa cuando se configura `envoy.load_shed_points.http1_server_abort_dispatch`. Si `active_request` es nullptr, solo se llama a onMessageBeginImpl(). Sin embargo, `onMessageBeginImpl` devolver\u00e1 directamente el estado ok si la secuencia ya se restableci\u00f3 y conduce a la referencia nullptr. El restablecimiento descendente puede ocurrir durante el restablecimiento ascendente de H/2. Como resultado, Envoy puede bloquearse. Este problema se ha solucionado en las versiones 1.32.3, 1.31.5, 1.30.9 y 1.29.12. Se recomienda a los usuarios que actualicen la versi\u00f3n. Los usuarios que no puedan actualizar pueden deshabilitar el punto de desconexi\u00f3n de carga `http1_server_abort_dispatch` o usar un umbral alto."
