CVE-2023-26556

CVE-2023-26556 affects io.finnet tss-lib prior to 2.0.0. The vulnerability arises from a timing side-channel leak in the scalar-multiplication code path used by ECDSA key generation, relying on Go’s crypto/elliptic implementation which is not constant time. Affected code path is identified in ecd...

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...
