CVSS: 8.1EPSS: 0%CPEs: 2EXPL: 0CVE-2020-10019 – Buffer Overflow in USB DFU requested length
https://notcve.org/view.php?id=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 2.1.0 and later versions. USB DFU presenta un potencial desbordamiento del búfer donde la longitud requerida (wLength) no es comparada con el tamaño del búfer. Esto podría ser usado por un host USB malicioso para explotar el desbordamiento del búfer. • https://docs.zephyrproject.org/latest/security/vulnerabilities.html#cve-2020-10019 https://github.com/zephyrproject-rtos/zephyr/pull/23190 https://github.com/zephyrproject-rtos/zephyr/pull/23457 https://github.com/zephyrproject-rtos/zephyr/pull/23460 https://zephyrprojectsec.atlassian.net/browse/ZEPSEC-25 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

zephyr-rtos version 1.12.0 contains a NULL base pointer reference vulnerability in sys_ring_buf_put(), sys_ring_buf_get() that can result in CPU Page Fault (error code 0x00000010). This attack appear to be exploitable via a malicious application call the vulnerable kernel APIs (system sys_ring_buf_get() and sys_ring_buf_put). zephyr-rtos 1.12.0 contiene una vulnerabilidad de desreferencia de puntero NULL en sys_ring_buf_put() y sys_ring_buf_get() que puede resultar en un fallo de página de CPU (código de error 0x00000010). El ataque parece ser explotable si una aplicación maliciosa llama a las API (sys_ring_buf_get() y sys_ring_buf_put del sistema) del kernel vulnerable. • https://github.com/zephyrproject-rtos/zephyr/issues/7638 • CWE-476: NULL Pointer Dereference •
