GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

GSD-2023-33242

Vulnerability from gsd - Updated: 2023-12-13 01:20
Details
Crypto wallets implementing the Lindell17 TSS protocol might allow an attacker to extract the full ECDSA private key by exfiltrating a single bit in every signature attempt (256 in total) because of not adhering to the paper's security proof's assumption regarding handling aborts after a failed signature.
