Résumé
Polkadot Frontier contains silent failure in Curve25519 arithmetic precompiles with malformed points
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Polkadot Frontier is an Ethereum and EVM compatibility layer for Polkadot and Substrate. In versions prior to commit 36f70d1, the Curve25519Add and Curve25519ScalarMul precompiles incorrectly handle invalid Ristretto point representations. Instead of returning an error, they silently treat invalid input bytes as the Ristretto identity element, leading to potentially incorrect cryptographic results. This is fixed in commit 36f70d1.
