CVE-2018-20821

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).

CVE-2018-19839

In LibSass prior to 3.5.5, the function handle_error in sass_context.cpp allows attackers to cause a denial-of-service resulting from a heap-based buffer over-read via a crafted sass file.

CVE-2019-6286

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.

CVE-2018-19797

In LibSass 3.5.5, a NULL Pointer Dereference in the function Sass::Selector_List::populate_extends in SharedPtr.hpp (used by ast.cpp and ast_selectors.cpp) may cause a Denial of Service (application crash) via a crafted sass input file.

CVE-2018-20822

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).

CVE-2018-19838

In LibSass prior to 3.5.5, functions inside ast.cpp for IMPLEMENT_AST_OPERATORS expansion allow attackers to cause a denial-of-service resulting from stack consumption via a crafted sass file, as demonstrated by recursive calls involving clone(), cloneChildren(), and copy().

CVE-2019-6284

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

CVE-2018-19837

In LibSass prior to 3.5.5, Sass::Eval::operator()(Sass::Binary_Expression*) inside eval.cpp allows attackers to cause a denial-of-service resulting from stack consumption via a crafted sass file, because of certain incorrect parsing of '%' as a modulo operator in parser.cpp.

CVE-2019-6283

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

CVE-2018-20190

In LibSass 3.5.5, a NULL Pointer Dereference in the function Sass::Eval::operator()(Sass::Supports_Operator*) in eval.cpp may cause a Denial of Service (application crash) via a crafted sass input file.

CVE-2019-18797

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

CVE-2019-18799

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

CVE-2019-18798

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

CVE-2018-19218

In LibSass 3.5-stable, there is an illegal address access at Sass::Parser::parse_css_variable_value_token that will lead to a DoS attack.

CVE-2018-19826

In inspect.cpp in LibSass 3.5.5, a high memory footprint caused by an endless loop (containing a Sass::Inspect::operator()(Sass::String_Quoted*) stack frame) may cause a Denial of Service via crafted sass input files with stray '&' or '/' characters. NOTE: Upstream comments indicate this issue is c...

CVE-2018-19219

In LibSass 3.5-stable, there is an illegal address access at Sass::Eval::operator that will lead to a DoS attack.
