https://notcve.org/view.php?id=CVE-2020-10648
Das U-Boot through 2020.01 allows attackers to bypass verified boot restrictions and subsequently boot arbitrary images by providing a crafted FIT image to a system configured to boot the default configuration. Das U-Boot versiones hasta 2020.01, permite a atacantes omitir restricciones de arranque verificadas y posteriormente iniciar imágenes arbitrarias al proporcionar una imagen FIT diseñada a un sistema configurado para iniciar la configuración predeterminada. • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00030.html http://www.openwall.com/lists/oss-security/2020/03/18/5 https://github.com/u-boot/u-boot/commits/master https://labs.f-secure.com/advisories/das-u-boot-verified-boot-bypass • CWE-20: Improper Input Validation •
CVE-2020-8432
https://notcve.org/view.php?id=CVE-2020-8432
In Das U-Boot through 2020.01, a double free has been found in the cmd/gpt.c do_rename_gpt_parts() function. Double freeing may result in a write-what-where condition, allowing an attacker to execute arbitrary code. NOTE: this vulnerablity was introduced when attempting to fix a memory leak identified by static analysis. En Das U-Boot hasta versión 2020.01, se ha encontrado una doble liberación en la función do_rename_gpt_parts() del archivo cmd/gpt.c. Una doble liberación puede resultar en una condición write-what-where, permitiendo a un atacante ejecutar código arbitrario. • http://lists.opensuse.org/opensuse-security-announce/2020-11/msg00030.html https://www.mail-archive.com/u-boot%40lists.denx.de/msg354060.html https://www.mail-archive.com/u-boot%40lists.denx.de/msg354114.html • CWE-415: Double Free CWE-787: Out-of-bounds Write •
