CVE-2023-44378

CVE-2023-44378 affects gnark (Go zk-SNARK library) prior to v0.9.0. For some in-circuit values, there can be two valid bit decompositions: the canonical a and a second decomposition for a+r caused by field overflow. This can enable incorrect comparisons using frontend.API.Cmp/IsLess (e.g., provin...

CVE-2023-44378 gnark vulnerable to unsoundness in variable comparison/non-unique binary decomposition

gnark is a zk-SNARK library that offers a high-level API to design circuits. Prior to version 0.9.0, for some in-circuit values, it is possible to construct two valid decomposition to bits. In addition to the canonical decomposition of a, for small values there exists a second decomposition for a...
