cggmp24 and cggmp21 are vulnerable to signature forgery through altered presignatures

Impact This attack is against presignatures used in very specific context: Presignatures + HD wallets derivation: security level reduces to 85 bits \ Previously users could generate a presignature, and then choose a HD derivation path while issuing a partial signature via...

cggmp21 安全漏洞

cggmp21 is a Rust library open-sourced by Lockness. A security vulnerability exists in cggmp21 versions 0.6.3 and earlier and 0.7.0-alpha.1, which stems from improper use of pre-signatures in a manner that may result in reduced security...

CVE-2025-66017: Use of a Broken or Risky Cryptographic Algorithm

CGGMP24 is a state-of-art ECDSA TSS protocol that supports 1-round signing requires 3 preprocessing rounds, identifiable abort, and a key refresh protocol. In versions 0.6.3 and prior of cggmp21 and version 0.7.0-alpha.1 of cggmp24, presignatures can be used in the way that significantly reduces...

cggmp21 数据伪造问题漏洞

cggmp21 is a Rust library open-sourced by Lockness. A data forgery issue vulnerability exists in versions prior to cggmp21 0.6.3, which stems from a missing check in the ZK proof that could lead to a malicious signer reconstructing the full private key...

GHSA-H24C-6P6P-M3VX tss-lib leaks secret keys in response to incorrectly constructed Paillier moduli

Impact The specification of the GG18 threshold ECDSA signature protocol contains a vulnerability allowing an attacker to recover the shared secret key. If a participant generates a Paillier modulus N containing small factors less than 2^100 they can interact with other participants in the signing...
