There is a stack consumption issue in LibSass 3.4.5 that is triggered in the function Sass::Eval::operator() in eval.cpp. It will lead to a remote denial of service attack.
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
