Starting in version 1.3.12 and prior to version 1.5.3, since LLL IR has no Turing-incompletness restrictions, it is compiled to a loop with a much more late exit condition. It leads to a loss of funds or other unwanted behavior if the loop body contains it. However, more real-life use cases like iterating over an array are not affected. No contracts were affected by this issue, which was fixed in version 1.5.3. Upgrading and redeploying affected contracts is the only way to avoid the vulnerability."

A partir de la versión 1.3.12 y antes de la versión 1.5.3, dado que LLL IR no tiene restricciones de incompletitud de Turing, se compila en un bucle con una condición de salida mucho más tardía. Conduce a una pérdida de fondos u otro comportamiento no deseado si el cuerpo del bucle lo contiene. Sin embargo, otros casos de uso de la vida real, como iterar sobre una matriz, no se ven afectados. Ningún contrato se vio afectado por este problema, que se solucionó en la versión 1.5.3. Actualizar y reimplementar los contratos afectados es la única manera de evitar la vulnerabilidad."
