Descriptions

STMicroelectronics STSAFE-A1xx middleware before 3.3.7 allows MCU code execution if an adversary has the ability to read from and write to the I2C bus. This is caused by an StSafeA_ReceiveBytes buffer overflow in the X-CUBE-SAFEA1 Software Package for STSAFE-A sample applications (1.2.0), and thus can affect user-written code that was derived from a published sample application.

El middleware STMicroelectronics STSAFE-A1xx anterior a 3.3.7 permite la ejecución de código MCU si un adversario tiene la capacidad de leer y escribir en el bus I2C. Esto se debe a un desbordamiento de búfer StSafeA_ReceiveBytes en el paquete de software X-CUBE-SAFEA1 para aplicaciones de muestra STSAFE-A (1.2.0) y, por lo tanto, puede afectar el código escrito por el usuario que se derivó de una aplicación de muestra publicada.
