      "value": "A flaw was found in Undertow. When an AJP request is sent that exceeds the max-header-size attribute in ajp-listener, JBoss EAP is marked in an error state by mod_cluster in httpd, causing JBoss EAP to close the TCP connection without returning an AJP response. This happens because mod_proxy_cluster marks the JBoss EAP instance as an error worker when the TCP connection is closed from the backend after sending the AJP request without receiving an AJP response, and stops forwarding. This issue could allow a malicious user could to repeatedly send requests that exceed the max-header-size, causing a Denial of Service (DoS)."

      "value": "Se encontr\u00f3 una falla en Undertow. Cuando se env\u00eda una solicitud AJP que excede el atributo max-header-size en ajp-listener, mod_cluster marca JBoss EAP en estado de error en httpd, lo que hace que JBoss EAP cierre la conexi\u00f3n TCP sin devolver una respuesta AJP. Esto sucede porque mod_proxy_cluster marca la instancia de JBoss EAP como un trabajador de error cuando la conexi\u00f3n TCP se cierra desde el backend despu\u00e9s de enviar la solicitud AJP sin recibir una respuesta AJP y deja de reenviar. Este problema podr\u00eda permitir que un usuario malintencionado env\u00ede repetidamente solicitudes que superen el tama\u00f1o m\u00e1ximo del encabezado, provocando una Denegaci\u00f3n de Servicio (DoS)."
