Information Disclosure

github.com/bnb-chain/tss-lib is vulnerable to Information Disclosure. An attacker is able to steal the secret key shares of other participants in the signing protocol. This could happen if the attacker generates a Paillier modulus N containing small factors less than 2^100. The master key can the...

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...
