gnark is a zero-knowledge proof system framework. In version 0.12.0, there is a potential denial of service vulnerability when computing scalar multiplication is using the fake-GLV algorithm. This is because the algorithm didn't converge quickly enough for some of the inputs. This issue has been patched in version 0.13.0.
