Descriptions

An integer underflow may occur due to lack of check when received data length from font_mgr_qsee_request_service is bigger than the minimal value of the segment header, which may result in a buffer overflow, in Snapdragon Automobile, Snapdragon Mobile, Snapdragon Wear in MDM9206, MDM9607, MDM9650, SD 210/SD 212/SD 205, SD 425, SD 430, SD 450, SD 625, SD 650/52, SD 820, SD 820A, SD 835, SD 845, SD 850.

Puede producirse un subdesbordamiento de enteros debido a la falta de comprobación cuando la longitud de los datos recibidos de font_mgr_qsee_request_service es mayor que el valor mínimo de la cabecera de segmento, lo que puede dar lugar a un desbordamiento del búfer, en Snapdragon Automobile, Snapdragon Mobile, Snapdragon Wear en MDM9206, MDM9607, MDM9650, SD 210/SD 212/SD 205, SD 425, SD 430, SD 450, SD 625, SD 650/52, SD 820, SD 820A, SD 835, SD 845, SD 850.
