Although the mechanism malfunctions and an error occurs during the runtime with the stack trace being issued, the software process is not properly terminated. The software client is still attempting to maintain the connection even though the network connection information is being reset live. In that insecure mode, the \"FrmAdvancedProtection\" component crashes, but the process continues to run with different errors and process corruptions. This local corruption vulnerability can be exploited by local attackers."

Aunque el mecanismo no funciona correctamente y el error ocurre durante el tiempo de ejecución con la emisión del seguimiento de la pila, el proceso del software no se finaliza correctamente. El cliente del software sigue intentando mantener la conexión incluso aunque la conexión a la red se está restableciendo al mismo tiempo. En ese modo inseguro, el componente \"FrmAdvancedProtection\" se cierra inesperadamente, pero el proceso continúa ejecutándose con diferentes errores y corrupciones del proceso. Esta vulnerabilidad de corrupción local puede ser explotada por atacantes locales."
