An issue exists in the _send_secure_msg() function of Yubico yubihsm-shell up to and including 2.0.3. The function does not correctly validate the embedded length field of an authenticated message received from the device. Out-of-bounds reads performed by aes_remove_padding() can crash the running process, depending on the memory layout. This could be used by an malicious user to cause a client-side denial of service. The yubihsm-shell project is included in the YubiHSM 2 SDK product.
