Descriptions
The Dumper method in Data::Dumper before 2.154, as used in Perl 5.20.1 and earlier, allows context-dependent attackers to cause a denial of service (stack consumption and crash) via an Array-Reference with many nested Array-References, which triggers a large number of recursive calls to the DD_dump function.
El método Dumper en Data::Dumper anterior a 2.154, utilizado en Perl 5.20.1 y anteriores, permite a atacantes dependientes de contexto causar una denegación de servicio (consumo de la pila y caída) a través de una referencia de array con muchas referencias de array anidadas, lo que provoca un número grande de llamadas recursivas a la función DD_dump.
A stack overflow was discovered when serializing data via the Data::Dumper extension which is part of Perl-Core. By using the "Dumper" method on a large Array-Reference which recursively contains other Array-References, it is possible to cause many recursive calls to the DD_dump native function and ultimately exhaust all available stack memory.
