CVE-2021-32489 (GCVE-0-2021-32489)

Vulnerability from cvelistv5 – Published: 2021-05-10 21:20 – Updated: 2024-08-03 23:17
VLAI
Summary
An issue was discovered in the _send_secure_msg() 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 response_msg.st.len=8 can be accepted but triggers an integer overflow, which causes CRYPTO_cbc128_decrypt (in OpenSSL) to encounter an undersized buffer and experience a segmentation fault. The yubihsm-shell project is included in the YubiHSM 2 SDK product.
