Das U-Boot verified boot bypass

Summary 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...

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 CONFIGENVAES=y read environment variables from disk as the encrypte...

CVE-2017-3226

CVE-2017-3226 concerns Das U-Boot’s AES-CBC environment encryption (CONFIG_ENV_AES=y). A crafted two‑byte sequence in the encrypted environment data can trigger an error during environment variable parsing, which is improperly handled and leads to an immediate process termination with a debugging...

CVE-2017-3225

CVE-2017-3225 concerns Das U-Boot, a device bootloader that reads configuration from an AES-CBC encrypted file. The vulnerability stems from U-Boot using a zero initialization vector (IV) in AES-CBC, which enables dictionary-like attacks on encrypted data to learn information about the ciphertext...
