GHSA-MJQV-XHGM-GX8C IO FinNet tss-lib vulnerable to timing attack from non-constant time scalar arithmetic

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...

CVE-2023-26556

io.finnet tss-lib before 2.0.0 can leak a secret key via a timing side-channel attack because it relies on the scalar-multiplication implementation in Go crypto/elliptic, which is not constant time there is an if statement in a loop. One leak is in ecdsa/keygen/round2.go. bnb-chain/tss-lib and...
