Summary		(es) NanaZip es un archivador de ficheros de código abierto. A partir de la versión 5.0.1252.0 y antes de la versión 6.0.1630.0, las cadenas circulares 'NextOffset' provocan un bucle infinito, y los directorios profundamente anidados provocan una recursión ilimitada (desbordamiento de pila) en el analizador de archivos ROMFS. La versión 6.0.1630.0 corrige el problema.
