This can cause an application crash or on some platforms even the execution of remote code. If your application is used in open networks or there are untrusted nodes in the network it is highly recommend to apply the patch. This was patched with commit 033ab5b. Users of version 1.4.x should upgrade to version 1.4.3 when available. As a workaround changes of commit 033ab5b can be applied to older versions."}, {"lang": "es", "value": "En libIEC61850 versiones anteriores a 1.4.3, cuando un mensaje es recibido con un campo de longitud de mensaje COTP con valor menor a 4, se producir\u00e1 un subdesbordamiento de enteros conllevando a un desbordamiento del b\u00fafer en la pila. Esto puede causar un bloqueo de la aplicaci\u00f3n o, en algunas plataformas, inclusive una ejecuci\u00f3n de c\u00f3digo remota. Si su aplicaci\u00f3n es utilizada en redes abiertas o si existen nodos en la red que no son confiables, se recomienda altamente aplicar el parche. Esto fue parcheado con el commit 033ab5b. Los usuarios de la versi\u00f3n 1.4.x deben actualizar a la versi\u00f3n 1.4.3 cuando est\u00e9 disponible.
