Descriptions

An exploitable heap overflow vulnerability exists in the Fiddle::Function.new "initialize" function functionality of Ruby. In Fiddle::Function.new "initialize" heap buffer "arg_types" allocation is made based on args array length. Specially constructed object passed as element of args array can increase this array size after mentioned allocation and cause heap overflow.

Existe una vulnerabilidad explotable de desbordamiento de memoria dinámica en la funcionalidad Fiddle::Function.new "initialize" de Ruby. En Fiddle::Function.new "initialize" la ubicación "arg_types" de la memoria dinámica del búfer se hace en base a la longitud de los args array. Un objeto especialmente construido pasado como un elemento de los args array puede incrementar el tamaño de este array después de haber mencionado la ubicación y provocar desbordamiento de memoria dinámica.
