Descriptions

The BigDecimal library in Ruby 1.8.6 before p369 and 1.8.7 before p173 allows context-dependent attackers to cause a denial of service (application crash) via a string argument that represents a large number, as demonstrated by an attempted conversion to the Float data type.

La librería BigDecimal en Ruby v1.8.6 anteriores p369 y v1.8.7, anteriores a p173 permite a los atacantes dependientes del contexto causar una denegación de servicio (caída de la aplicación) a través de un argumento de cadena de caracteres que representa un número largo, como se demuestra por un intento de conversión al tipo de dato Float.
