Summary
[none]
Details

An issue was discovered in the sendsecuremsg() function of Yubico yubihsm-shell through 2.0.3. The function does not correctly validate the embedded length field of an authenticated message received from the device because responsemsg.st.len=8 can be accepted but triggers an integer overflow, which causes CRYPTOcbc128decrypt (in OpenSSL) to encounter an undersized buffer and experience a segmentation fault. The yubihsm-shell project is included in the YubiHSM 2 SDK product.
