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."

En versiones anteriores al commit 36f70d1, las precompilaciones Curve25519Add y Curve25519ScalarMul gestionaban incorrectamente las representaciones de puntos de Ristretto no v\u00e1lidas. En lugar de devolver un error, trataban silenciosamente los bytes de entrada no v\u00e1lidos como el elemento de identidad de Ristretto, lo que pod\u00eda generar resultados criptogr\u00e1ficos incorrectos.
