Descriptions

In Symfony before versions 5.0.5 and 4.4.5, some properties of the Exception were not properly escaped when the `ErrorHandler` rendered it stacktrace. In addition, the stacktrace were displayed even in a non-debug configuration. The ErrorHandler now escape alls properties of the exception, and the stacktrace is only display in debug configuration. This issue is patched in symfony/http-foundation versions 4.4.5 and 5.0.5

En Symfony versiones anteriores a 5.0.5 y 4.4.5, algunas propiedades de la Excepción no fueron escapados apropiadamente cuando el "ErrorHandler" la renderizó en stacktrace. Además, el stacktrace fue desplegado incluso en una configuración sin depuración. ErrorHandler ahora escapa de todas las propiedades de la excepción, y el stacktrace se muestra solo en la configuración de depuración. Este problema está parcheado en Symfony/http-foundation versiones 4.4.5 y 5.0.5.
