Name of the Vulnerable Software and Affected Versions: io.finnet tss-lib versions prior to 2.0.0 bnb-chain/tss-lib versions prior to 2.0.0 thorchain/tss versions prior to 2.0.0 Description: The issue is related to a timing side-channel attack that can leak a secret key. This occurs because the...

Observable Discrepancy

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...

CVE-2023-26557

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-2023-26557

io.finnet tss-lib before 2.0.0 is vulnerable to a timing side-channel that can leak the lambda value of a private key because it uses Go big.Int in non-constant-time operations (Cmp, modular exponentiation, modular inverse). The issue affects tss-lib versions prior to 2.0.0 and is noted for bnb-c...

CVE-2022-47930

CVE-2022-47930 affects IO FinNet tss-lib prior to 2.0.0. The root cause is that the parameter ssid used to define a session id is not applied through the MPC implementation, and the Schnorr proof of knowledge in sch.go does not utilize a session id, context, or random nonce when generating the ch...

CVE-2022-47930

An issue was discovered in IO FinNet tss-lib before 2.0.0. The parameter ssid for defining a session id is not used through the MPC implementation, which makes replaying and spoofing of messages easier. In particular, the Schnorr proof of knowledge implemented in sch.go does not utilize a session...

CVE-2022-47931

CVE-2022-47931 affects IO FinNet tss-lib prior to 2.0.0, describing a collision of hash values in the library used for threshold ECDSA/EdDSA in multi-party signing. The connected documents identify the affected version range (before 2.0.0) and point to the v2.0.0 release as remediation, along wit...

GHSA-GP6J-VX54-5PMF Incorrect validation of parties IDs leaks secret keys in Secret-sharing scheme

Summary In the threshold signature scheme, participants start by dividing secrets into shares using a secret sharing scheme. The Verifiable Secret Sharing scheme generates shares from the user’s IDs but does not properly validate them. Using a malicious ID will make other users reveal their secre...
