Overview
Affected versions of this package are vulnerable to Improper Handling of Exceptional Conditions via the tee-supplicant process. An attacker can cause trusted applications to panic, leading to the reset of Platform Configuration Registers (PCRs) and potential disclosure of sensitive data by running a malicious tee-supplicant that returns unexpected response codes to secure storage operations. This allows manipulation of memory states and falsification of boot measurements.
