FKIE_CVE-2021-31616

Vulnerability from fkie_nvd - Published: 2021-05-06 13:15 - Updated: 2024-11-21 06:06
Severity ?
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Summary
Insufficient length checks in the ShapeShift KeepKey hardware wallet firmware before 7.1.0 allow a stack buffer overflow via crafted messages. The overflow in ethereum_extractThorchainSwapData() in ethereum.c can circumvent stack protections and lead to code execution. The vulnerable interface is reachable remotely over WebUSB.
