|---|---|---|
| github.com/binance-chain/tss-lib | < 1.3.6-0.20230324145555-bb6fb30bd3eball versions | 1.3.6-0.20230324145555-bb6fb30bd3eb |
| github.com/bnb-chain/tss-lib | < 1.3.6-0.20230324145555-bb6fb30bd3eb | 1.3.6-0.20230324145555-bb6fb30bd3eb |
| tss-lib | < 2.0.0 | 2.0.0 |
io.finnet tss-lib before 2.0.0 can leak the lambda value of a private key via a timing side-channel attack because it relies on Go big.Int, which is not constant time for Cmp, modular exponentiation, or modular inverse. An example leak is in crypto/paillier/paillier.go. (bnb-chain/tss-lib and thorchain/tss are also affected.)
