In versions 0.3.10 and prior, using the `sqrt` builtin can result in double eval vulnerability when the argument has side-effects. It can be seen that the `build_IR` function of the `sqrt` builtin doesn't cache the argument to the stack. As such, it can be evaluated multiple times (instead of retrieving the value from the stack). No vulnerable production contracts were found. Additionally, double evaluation of side-effects should be easily discoverable in client tests. As such, the impact is low. As of time of publication, no fixed versions are available.\n"}, {"lang": "es", "value": "Vyper es un lenguaje de contrato inteligente pit\u00f3nico para la m\u00e1quina virtual Ethereum. En las versiones 0.3.10 y anteriores, el uso de la funci\u00f3n incorporada `sqrt` puede generar una vulnerabilidad de doble evaluaci\u00f3n cuando el argumento tiene efectos secundarios. Se puede ver que la funci\u00f3n `build_IR` del incorporado `sqrt` no almacena en cach\u00e9 el argumento en la pila. Como tal, se puede evaluar varias veces (en lugar de recuperar el valor de la pila). No se encontraron contratos de producci\u00f3n vulnerables. Adem\u00e1s, la doble evaluaci\u00f3n de los efectos secundarios deber\u00eda poder descubrirse f\u00e1cilmente en las pruebas de los clientes. Como tal, el impacto es bajo.
