Descriptions

active_support/core_ext/hash/conversions.rb in Ruby on Rails before 2.3.15, 3.0.x before 3.0.19, 3.1.x before 3.1.10, and 3.2.x before 3.2.11 does not properly restrict casts of string values, which allows remote attackers to conduct object-injection attacks and execute arbitrary code, or cause a denial of service (memory and CPU consumption) involving nested XML entity references, by leveraging Action Pack support for (1) YAML type conversion or (2) Symbol type conversion.

active_support/core_ext/hash/conversions.rb en Ruby on Rails anterior a v2.3.15, v3.0.x anterior a v3.0.19, v3.1.x anterior a v3.1.10, y v3.2.x anterior a v3.2.11 no restringe adecuadamente el "casting" de las variables de tipo cadena, lo que permite a atacantes remotos llevar a cabo ataques de inyección de objetos y la ejecución de código arbitrario o provocar una denegación de servicio (consumo de memoria y CPU) involucrando a referencias de entidades XML anidadas, aprovechando el soporte de Action Pack para lso tipos de conversion (1) YAML o (2) Symbol.
