CVSS: 7.7EPSS: 0%CPEs: 1EXPL: 1CVE-2022-2347 – Unchecked Download size in Uboot
https://notcve.org/view.php?id=CVE-2022-2347
23 Sep 2022 — 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... • https://seclists.org/oss-sec/2022/q3/41 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

20 Jul 2022 — squashfs filesystem implementation of U-Boot versions from v2020.10-rc2 to v2022.07-rc5 contains a heap-based buffer overflow vulnerability due to a defect in the metadata reading process. Loading a specially crafted squashfs image may lead to a denial-of-service (DoS) condition or arbitrary code execution.

01 Jul 2022 — Das U-Boot from v2020.10 to v2022.07-rc3 was discovered to contain an out-of-bounds write via the function sqfs_readdir(). Se ha detectado que Das U-Boot desde versiones v2020.10 a v2022.07-rc3, contiene una escritura fuera de límites por medio de la función sqfs_readdir() It was discovered that U-Boot incorrectly handled certain USB DFU download setup packets. A local attacker could use this issue to cause U-Boot to crash, resulting in a denial of service, or possibly execute arbitrary code.

29 Jun 2022 — 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 It was discovered that U-Boot incorrectly handled... • https://github.com/u-boot/u-boot/commit/8f8c04bf1ebbd2f72f1643e7ad9617dafa6e5409 • CWE-787: Out-of-bounds Write •

16 May 2022 — 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.
