Tss Security Vulnerabilities

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/round_2.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-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-2023-22745

tpm2-tss is an open source software implementation of the Trusted Computing Group (TCG) Trusted Platform Module (TPM) 2 Software Stack (TSS2). In affected versions Tss2_RC_SetHandler and Tss2_RC_Decode both index into layer_handler with an 8 bit layer number, but the array only has...
