Detail
Vulnerability Note VU#166743Das U-Boot AES-CBC encryption implementation contains multiple vulnerabilitiesOverviewDas 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 and improper handling of an error condition may allow attacks against the underlying cryptographic implementation and allow an attacker to decrypt the data.
