Descriptions

The Fiddle::Handle implementation in ext/fiddle/handle.c in Ruby before 2.0.0-p648, 2.1 before 2.1.8, and 2.2 before 2.2.4, as distributed in Apple OS X before 10.11.4 and other products, mishandles tainting, which allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted string, related to the DL module and the libffi library. NOTE: this vulnerability exists because of a CVE-2009-5147 regression.

La implementación Fiddle::Handle en ext/fiddle/handle.c en Ruby en versiones anteriores a 2.0.0-p648, 2.1 en versiones anteriores a 2.1.8 y 2.2 en versiones anteriores a 2.2.4, según se distribuye en Apple OS X en versiones anteriores a 10.11.4 y otros productos, no maneja correctamente el tainting, lo que permite a atacantes dependientes del contexto ejecutar código arbitrario o causar una denegación de servicio (caída de aplicación) a través de una cadena manipulada, relacionado con el módulo DL y la librería libffi. NOTA: esta vulnerabilidad existe por una regresión de CVE-2009-5147.
