Descriptions

ZKsync Era is a layer 2 rollup that uses zero-knowledge proofs to scale Ethereum. Prior to version 1.3.10, there is a very specific pattern `f(a(),b()); check_if_a_executed_last()` in Yul that exposes a bug in evaluation order of Yul function arguments. This vulnerability has been fixed in version 1.3.10. As a workaround, update and redeploy affected contracts.

ZKsync Era es un paquete acumulativo de capa 2 que utiliza pruebas de conocimiento cero para escalar Ethereum. Antes de la versión 1.3.10, existía un patrón muy específico `f(a(),b()); check_if_a_executed_last()` en Yul que expone un error en el orden de evaluación de los argumentos de la función Yul. Esta vulnerabilidad se ha solucionado en la versión 1.3.10. Como workaround, actualice y vuelva a implementar los contratos afectados.
