This library may be used by the Azure IoT C SDK for communication between IoT Hub and IoT Hub devices. An attacker can cause an integer wraparound or under-allocation or heap buffer overflow due to vulnerabilities in parameter checking mechanism, by exploiting the buffer length parameter in Azure C SDK, which may lead to remote code execution. Requirements for RCE are 1. Compromised Azure account allowing malformed payloads to be sent to the device via IoT Hub service, 2. By passing IoT hub service max message payload limit of 128KB, and 3. Ability to overwrite code space with remote code.

El SDK de Azure IoT C puede usar esta biblioteca para la comunicaci\u00f3n entre IoT Hub y los dispositivos IoT Hub. Un atacante puede provocar una envoltura de enteros, una asignaci\u00f3n insuficiente o un desbordamiento de b\u00fafer de almacenamiento din\u00e1mico debido a vulnerabilidades en el mecanismo de verificaci\u00f3n de par\u00e1metros, al explotar el par\u00e1metro de longitud del b\u00fafer en Azure C SDK, lo que puede conducir a la ejecuci\u00f3n remota de c\u00f3digo.
