Nimiq 数据伪造问题漏洞

Nimiq is an open-source implementation of the Albatross protocol in Rust. Prior to Nimiq 1.3.0, there was a vulnerability related to data manipulation. This vulnerability stemmed from the UpdateValidator transaction in the nimiq-transaction where the was set with newvotingkey=Some…, but the...

gnark's Groth16 commitment extension unsound for more than one commitment

Description The summary is that the proof of knowledge associated to a commitment is crucial to bind the commitment to the actual circuit variables that were supposed to be committed. However, the same σ is used for all proofs of knowledge for the commitments, which allows mixing between them,...

GHSA-C58H-QV6G-FW74 IO FinNet tss-lib vulnerable to replay attacks involving proofs

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...
