A crafted self-referential DOS partition table will cause all Das U-Boot versions through 2019.07-rc4 to infinitely recurse, causing the stack to grow infinitely and eventually either crash or overwrite other data. Una tabla de partición autorreferencial DOS especialmente diseñada, causará que todas las versiones hasta 2019.07-rc4 de Das U-Boot se repitan infinitamente, haciendo que la pila crezca infinitamente y eventualmente se bloquee o sobrescriba otros datos. • https://cert-portal.siemens.com/productcert/pdf/ssa-618620.pdf https://gist.github.com/deephooloovoo/d91b81a1674b4750e662dfae93804d75 https://github.com/u-boot/u-boot/commits/master https://lists.denx.de/pipermail/u-boot/2019-July/375512.html • CWE-674: Uncontrolled Recursion •

https://notcve.org/view.php?id=CVE-2018-3968
An exploitable vulnerability exists in the verified boot protection of the Das U-Boot from version 2013.07-rc1 to 2014.07-rc2. The affected versions lack proper FIT signature enforcement, which allows an attacker to bypass U-Boot's verified boot and execute an unsigned kernel, embedded in a legacy image format. To trigger this vulnerability, a local attacker needs to be able to supply the image to boot. Existe una vulnerabilidad explotable en la protección verificada de arranque de Das U-Boot, desde la versión 2013.07-rc1 hasta la 2014.07-rc2. Las versiones afectadas carecen de una aplicación adecuada de las firmas FIT, lo que permite que un atacante omita el arranque verificado de U-Boot y ejecute un kernel sin firmar, embebido en un formato de imagen heredado. • https://talosintelligence.com/vulnerability_reports/TALOS-2018-0633 • CWE-347: Improper Verification of Cryptographic Signature •

DENX U-Boot through 2018.09-rc1 has a remotely exploitable buffer overflow via a malicious TFTP server because TFTP traffic is mishandled. Also, local exploitation can occur via a crafted kernel image. DENX U-Boot hasta el 2018.09-rc1 tiene un desbordamiento de búfer explotable de forma remota mediante un servidor TFTP malicioso debido a que el tráfico TFTP se gestiona de manera incorrecta. Además, podría ocurrir una explotación local mediante una imagen de kernel manipulada. • http://www.openwall.com/lists/oss-security/2018/11/02/2 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

CVSS: 4.6EPSS: 0%CPEs: 1EXPL: 0CVE-2017-3225 – Das U-Boot's AES-CBC encryption feature uses a zero (0) initialization vector that may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the data
https://notcve.org/view.php?id=CVE-2017-3225
Das U-Boot is a device bootloader that can read its configuration from an AES encrypted file. For devices utilizing this environment encryption mode, U-Boot's use of a zero initialization vector may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the data. Das U-Boot's AES-CBC encryption feature uses a zero (0) initialization vector. This allows an attacker to perform dictionary attacks on encrypted data produced by Das U-Boot to learn information about the encrypted data. Das U-Boot es un bootloader de dispositivos que puede leer su configuración desde un archivo cifrado por AES. • http://www.securityfocus.com/bid/100675 https://www.kb.cert.org/vuls/id/166743 • CWE-310: Cryptographic Issues CWE-329: Generation of Predictable IV with CBC Mode •
