Original NVD Description

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.
