Descriptions

The mx4200_send function in the legacy MX4200 refclock in NTP before 4.2.8p10 and 4.3.x before 4.3.94 does not properly handle the return value of the snprintf function, which allows local users to execute arbitrary code via unspecified vectors, which trigger an out-of-bounds memory write.

La función mx4200_send en el refclock legado de MX4200 en NTP en versiones anteriores a 4.2.8p10 y 4.3.x en versiones anteriores a 4.3.94 no maneja correctamente el valor de retorno de la función snprintf, lo que permite a usuarios locales ejecutar código arbitrario a través de vectores no especificados, lo que desencadena una escritura de memoria fuera de límites.
