Stack overflow vulnerability in ast_selectors.cpp: in function Sass::ComplexSelector::has_placeholder in libsass:3.6.5-8-g210218, which can be exploited by attackers to cause a denial of service (DoS).

Stack Overflow vulnerability in libsass 3.6.5 via the CompoundSelector::has_real_parent_ref function.

LibSass before 3.6.3 allows a NULL pointer dereference in Sass::Parser::parseCompoundSelector in parser_selectors.cpp.

LibSass before 3.6.3 allows a heap-based buffer over-read in Sass::weaveParents in ast_sel_weave.cpp.

LibSass 3.6.1 has uncontrolled recursion in Sass::Eval::operator()(Sass::Binary_Expression*) in eval.cpp.

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 parsing component in LibSass through 3.5.5 allows attackers to cause a denial-of-service (uncontrolled recursion in Sass::Parser::parse_css_variable_value in parser.cpp).

In LibSass 3.5.5, a heap-based buffer over-read exists in Sass::Prelexer::skip_over_scopes in prelexer.hpp when called from Sass::Parser::parse_import(), a similar issue to CVE-2018-11693.

In LibSass 3.5.5, a heap-based buffer over-read exists in Sass::Prelexer::alternatives in prelexer.hpp.
