FKIE_CVE-2023-27892

Vulnerability from fkie_nvd - Published: 2023-05-02 21:15 - Updated: 2025-01-30 17:15
Severity ?
3.8 (Low) - CVSS:3.1/AV:P/AC:H/PR:H/UI:N/S:U/C:H/I:N/A:N
5.7 (Medium) - CVSS:3.1/AV:P/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:H
Summary
Insufficient length checks in the ShapeShift KeepKey hardware wallet firmware before 7.7.0 allow a global buffer overflow via crafted messages. Flaws in cf_confirmExecTx() in ethereum_contracts.c can be used to reveal arbitrary microcontroller memory on the device screen or crash the device. With physical access to a PIN-unlocked device, attackers can extract the BIP39 mnemonic secret from the hardware wallet.
