The install.c module in the Pengutronix RAUC update client prior to version 1.5 has a Time-of-Check Time-of-Use vulnerability, where signature verification on an update file takes place before the file is reopened for installation. An attacker who can modify the update file just before it is reopened can install arbitrary code on the device.

    The vulnerability is a Time-of-Check-Time-of-Use (CWE-367) issue which allows an attacker with access to the firmware update file to overwrite it after it has been verified (but before installation is completed), which consequently allows installing an arbitrary firmware update, bypassing the cryptographic signature check mechanism.
