Descriptions

The dl module in Ruby 1.8.5 and earlier, 1.8.6 through 1.8.6-p286, 1.8.7 through 1.8.7-p71, and 1.9 through r18423 does not check "taintness" of inputs, which allows context-dependent attackers to bypass safe levels and execute dangerous functions by accessing a library using DL.dlopen.

El módulo dl en Ruby versiones 1.8.5 y anteriores, versiones 1.8.6 hasta 1.8.6-p286, versiones 1.8.7 hasta 1.8.7-p71, y versiones 1.9 a r18423 no comprueba la "taintness" de entradas, lo que permite a los atacantes dependiendo del contexto omitir los niveles seguros y ejecutar funciones peligrosas mediante el acceso a una biblioteca usando DL.dlopen.
