CVSS: 7.7EPSS: 0%CPEs: 1EXPL: 1CVE-2022-2347 – Unchecked Download size in Uboot
https://notcve.org/view.php?id=CVE-2022-2347
There exists an unchecked length field in UBoot. The U-Boot DFU implementation does not bound the length field in USB DFU download setup packets, and it does not verify that the transfer direction corresponds to the specified command. Consequently, if a physical attacker crafts a USB DFU download setup packet with a `wLength` greater than 4096 bytes, they can write beyond the heap-allocated request buffer. Se presenta un campo de longitud no comprobado en UBoot. La implementación de U-Boot DFU no vincula el campo de longitud en los paquetes de configuración de descarga de USB DFU, y no verifica que la dirección de transferencia sea correspondida con el comando especificado. • https://seclists.org/oss-sec/2022/q3/41 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

In Das U-Boot through 2022.07-rc5, an integer signedness error and resultant stack-based buffer overflow in the "i2c md" command enables the corruption of the return address pointer of the do_i2c_md function. En Das U-Boot versiones hasta 2022.07-rc5, un error de firma de enteros y el desbordamiento de búfer resultante en la región stack de la memoria en el comando "i2c md" permite una corrupción del puntero de la dirección de retorno de la función do_i2c_md • https://github.com/u-boot/u-boot/commit/8f8c04bf1ebbd2f72f1643e7ad9617dafa6e5409 https://lists.denx.de/pipermail/u-boot/2022-June/486113.html https://source.denx.de/u-boot/u-boot/-/commit/8f8c04bf1ebbd2f72f1643e7ad9617dafa6e5409 • CWE-787: Out-of-bounds Write •

nfs_lookup_reply in net/nfs.c in Das U-Boot through 2022.04 (and through 2022.07-rc2) has an unbounded memcpy with a failed length check, leading to a buffer overflow. NOTE: this issue exists because of an incorrect fix for CVE-2019-14196. La función nfs_lookup_reply en el archivo net/nfs.c en Das U-Boot hasta 2022.04 (y hasta 2022.07-rc2), presenta un memcpy no limitado con una comprobación de longitud fallida, conllevando a un desbordamiento del búfer. NOTA: este problema se presenta debido a una corrección incorrecta de CVE-2019-14196 • https://github.com/u-boot/u-boot/commit/5d14ee4e53a81055d34ba280cb8fd90330f22a96 https://lists.denx.de/pipermail/u-boot/2022-May/483952.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DF62MVMH3QUGMBDCB3DY2ERQ6EBHTADB https://securitylab.github.com/research/uboot-rce-nfs-vulnerability https://source.denx.de/u-boot/u-boot/-/commit/bdbf7a05e26f3c5fd437c99e2755ffde186ddc80 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
