An issue exists in the _send_secure_msg() function of yubihsm-shell up to and including 2.0.2. The function does not validate the embedded length field of a message received from the device. This could lead to an oversized memcpy() call that will crash the running process. This could be used by an malicious user to cause a denial of service.
