The CodeWrights HART Device Type Manager (DTM) library in Emerson HART DTM before 1.4.181 allows physically proximate attackers to cause a denial of service (DTM outage and FDT Frame application hang) by transmitting crafted response packets on the 4-20 mA current loop.
La libraría CodeWrights HART Device Type Manager (DTM) en Emerson HART DTM anterior a 1.4.181 permite a atacantes físicamente próximos causar una denegación de servicio (interrupción de DTM y cuelgue de la aplicación FDT Frame) mediante la transmisión de paquetes de respuesta manipulados en el bucle actual 4-20 mA.
