Zephyr Input Validation Error Vulnerability (CNVD-2020-29631)

Zephyr is an open source, small, scalable real-time operating system from the Linux Foundation. Zephyr suffers from an input validation error vulnerability that stems from the program not performing parameter validation when making multiple system calls. No details of the vulnerability are...

Zephyr Trust Management Issues Vulnerabilities

Zephyr is an open source, small, scalable real-time operating system from the Linux Foundation. A trust management issue vulnerability exists in the UpdateHub module in Zephyr 2.1.0 and later fixed in version 2.2.0, which stems from the program disabling DTLS peer checking. An attacker could use...

Zephyr Input Validation Error Vulnerability (CNVD-2020-35003)

Zephyr is an open source, small, scalable real-time operating system from the Linux Foundation. An input validation error vulnerability exists in the Kscan subsystem in Zephyr 2.1.0 and later fixed in version 2.2.0, which stems from the program failing to perform sufficient parameter validation...

Zephyr USB Mass Storage Buffer Overflow Vulnerability

Zephyr is an open source, small, scalable real-time operating system from the Linux Foundation in the U.S. USB Mass Storage is one of the USB mass storage components. A buffer overflow vulnerability exists in USB Mass Storage in Zephyr versions 1.14.1 and later and 2.1.0 and later. An attacker...

Zephyr Code Execution Vulnerability

Zephyr is an open source, small, scalable real-time operating system from the Linux Foundation. A security vulnerability exists in Zephyr versions 2.1.0 and later and 2.2.0 and later. An attacker can exploit this vulnerability by sending a malformed JSON file to the UpdateHub server to cause a...

Zephyr Buffer Overflow Vulnerability (CNVD-2020-35000)

Zephyr is an open source, small, scalable real-time operating system from the Linux Foundation. A buffer overflow vulnerability exists in the USB DFU in Zephyr version 1.14.1 and later and version 2.1.0 and later. A remote attacker could exploit this vulnerability to execute code...

CVE-2020-10060

In updatehubprobe, 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...

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...

CVE-2020-10028

Multiple syscalls with insufficient argument validation See NCC-ZEP-006 This issue affects: zephyrproject-rtos zephyr version 1.14.0 and later versions. version 2.1.0 and later versions...

CVE-2020-10058

Multiple syscalls in the Kscan subsystem perform insufficient argument validation, allowing code executing in userspace to potentially gain elevated privileges. See NCC-ZEP-006 This issue affects: zephyrproject-rtos zephyr version 2.1.0 and later versions...

CVE-2020-10027

An attacker who has obtained code execution within a user thread is able to elevate privileges to that of the kernel. See NCC-ZEP-001 This issue affects: zephyrproject-rtos zephyr version 1.14.0 and later versions. version 2.1.0 and later versions...

CVE-2020-10023

The shell subsystem contains a buffer overflow, whereby an adversary with physical access to the device is able to cause a memory corruption, resulting in denial of service or possibly code execution within the Zephyr kernel. See NCC-NCC-019 This issue affects: zephyrproject-rtos zephyr version...

CVE-2020-10021

Out-of-bounds Write in the USB Mass Storage memoryWrite handler with unaligned Sizes See NCC-ZEP-024, NCC-ZEP-025, NCC-ZEP-026 This issue affects: zephyrproject-rtos zephyr version 1.14.1 and later versions. version 2.1.0 and later versions...

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 versi...

CVE-2020-10019

USB DFU has a potential buffer overflow where the requested length wLength is not checked against the buffer size. This could be used by a malicious USB host to exploit the buffer overflow. See NCC-ZEP-002 This issue affects: zephyrproject-rtos zephyr version 1.14.1 and later versions. version...
