How to fix?
github.com/Yubico/yubihsm-connector to version 3.0.1 or higher.
github.com/Yubico/yubihsm-connector is a YubiHSM Connector
Affected versions of this package are vulnerable to Improper Input Validation. An issue was discovered in the
/api/connector endpoint handler in
Yubico yubihsm-connector (in YubiHSM SDK before 2021.04). The handler did not validate the length of the request, which can lead to a state where yubihsm-connector becomes stuck in a loop waiting for the YubiHSM to send it data, preventing any further operations until the yubihsm-connector is restarted. An attacker can send 0, 1, or 2 bytes to trigger this.
