GHSA-9FVJ-XQR2-XWG8 gnark affected by denial of service when computing scalar multiplication using fake-GLV algorithm

Impact For optimizing the scalar multiplication algorithm in circuit for some curves, gnark uses fake-GLV algorithm in case the curve doesn't support true-GLV. For this to work, we need to compute the scalar decomposition using the Half GCD method in gnark-crypto. However, for some of the inputs...
