Prior to 3.4.1.15, a user with create udf privilege could upload a crafted shared library and install it as a user-defined function, such as eval, then execute arbitrary C code on the TDengine server side through database queries. This issue is fixed in version 3.4.1.15."

Antes de la versión 3.4.1.15, un usuario con privilegio de creación de UDF podría cargar una biblioteca compartida manipulada e instalarla como una función definida por el usuario, como eval, para luego ejecutar código C arbitrario en el lado del servidor de TDengine a través de consultas a la base de datos. Este problema está solucionado en la versión 3.4.1.15."
