LibSass 3.5.4 allows attackers to cause a denial-of-service (uncontrolled recursion in Sass::Complex_Selector::perform in ast.hpp and Sass::Inspect::operator in inspect.cpp).
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
