VAR-201810-1439
Vulnerability from variot - Updated: 2023-12-18 12:28A remote code execution vulnerability exists in the way that Azure IoT Hub Device Client SDK using MQTT protocol accesses objects in memory, aka "Azure IoT Device Client SDK Memory Corruption Vulnerability." This affects Hub Device Client SDK, Azure IoT Edge. Microsoft C SDK for Azure IoT is a C language based software development kit for developing Azure IoT (Internet of Things Platform) applications. An attacker could use this vulnerability to execute arbitrary code in the context of the currently logged-on user. A failed attack will result in a denial of service condition
