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') •
