CVSS: 9.8EPSS: 6%CPEs: 1EXPL: 0CVE-2020-10071 – Insufficient publish message length validation in MQTT
https://notcve.org/view.php?id=CVE-2020-10071
The Zephyr MQTT parsing code performs insufficient checking of the length field on publish messages, allowing a buffer overflow and potentially remote code execution. NCC-ZEP-031 This issue affects: zephyrproject-rtos zephyr version 2.2.0 and later versions. El código de análisis de Zephyr MQTT realiza una comprobación insuficiente del campo de longitud en los mensajes de publicación, lo que permite un desbordamiento del búfer y potencialmente una ejecución de código remota.

CVSS: 8.0EPSS: 0%CPEs: 1EXPL: 0CVE-2020-10060 – UpdateHub Might Dereference An Uninitialized Pointer
https://notcve.org/view.php?id=CVE-2020-10060
In updatehub_probe, right after JSON parsing is complete, objects\[1] is accessed from the output structure in two different places. If the JSON contained less than two elements, this access would reference unitialized stack memory. This could result in a crash, denial of service, or possibly an information leak. Provided the fix in CVE-2020-10059 is applied, the attack requires compromise of the server.
