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.
