CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 0CVE-2020-10067 – Integer Overflow In is_in_region Allows User Thread To Access Kernel Memory
https://notcve.org/view.php?id=CVE-2020-10067
A malicious userspace application can cause a integer overflow and bypass security checks performed by system call handlers. The impact would depend on the underlying system call and can range from denial of service to information leak to memory corruption resulting in code execution within the kernel. See NCC-ZEP-005 This issue affects: zephyrproject-rtos zephyr version 1.14.1 and later versions. version 2.1.0 and later versions. Una aplicación de espacio de usuario maliciosa puede causar un desbordamiento de enteros y omitir comprobaciones de seguridad llevadas a cabo por manejadores de llamadas del sistema. El impacto dependería de la llamada del sistema subyacente y puede variar desde una denegación de servicio hasta el filtrado de información para una corrupción de memoria, resultando en una ejecución de código dentro del kernel. • https://docs.zephyrproject.org/latest/security/vulnerabilities.html#cve-2020-10067 https://github.com/zephyrproject-rtos/zephyr/pull/23239 https://github.com/zephyrproject-rtos/zephyr/pull/23653 https://github.com/zephyrproject-rtos/zephyr/pull/23654 https://zephyrprojectsec.atlassian.net/browse/ZEPSEC-27 • CWE-190: Integer Overflow or Wraparound •
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.

CVSS: 5.8EPSS: 0%CPEs: 2EXPL: 0CVE-2020-10059 – UpdateHub Module Explicitly Disables TLS Verification
https://notcve.org/view.php?id=CVE-2020-10059
The UpdateHub module disables DTLS peer checking, which allows for a man in the middle attack. This is mitigated by firmware images requiring valid signatures. However, there is no benefit to using DTLS without the peer checking. See NCC-ZEP-018 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions. El módulo UpdateHub deshabilita la comprobación del peer DTLS, lo que permite un ataque de tipo man in the middle. • https://docs.zephyrproject.org/latest/security/vulnerabilities.html#cve-2020-10059 https://github.com/zephyrproject-rtos/zephyr/pull/24954 https://github.com/zephyrproject-rtos/zephyr/pull/24997 https://github.com/zephyrproject-rtos/zephyr/pull/24999 https://zephyrprojectsec.atlassian.net/browse/ZEPSEC-36 • CWE-295: Improper Certificate Validation •
