Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2017-3226 unimportant priority: Debian including 1 source packages (u-boot), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): open 5.
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.
