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.

CVSS: 6.4EPSS: 0%CPEs: 1EXPL: 0CVE-2017-3226 – Das U-Boot's AES-CBC encryption feature improperly handles an error condition and may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the data
https://notcve.org/view.php?id=CVE-2017-3226
Das U-Boot is a device bootloader that can read its configuration from an AES encrypted file. Devices that make use of Das U-Boot's AES-CBC encryption feature using environment encryption (i.e., setting the configuration parameter CONFIG_ENV_AES=y) read environment variables from disk as the encrypted disk image is processed. An attacker with physical access to the device can manipulate the encrypted environment data to include a crafted two-byte sequence which triggers an error in environment variable parsing. This error condition is improperly handled by Das U-Boot, resulting in an immediate process termination with a debugging message.
