Esto permite que atacantes remotos provoquen una denegaci\u00f3n de servicio (cierre inesperado de la aplicaci\u00f3n) o, posiblemente, otro tipo de impacto sin especificar mediante un archivo ELF. Esto se relaciona con parse_die y parse_line_table, tal y como demuestra una sobrelectura de b\u00fafer basada en memoria din\u00e1mica (heap)."
