19 security issues in buster high

There are 19 open security issues in buster.

9 important issues:

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-2018-19219: In LibSass 3.5-stable, there is an illegal address access at Sass::Eval::operator that will lead to a DoS attack.
CVE-2017-11605: There is a heap based buffer over-read in LibSass 3.4.5, related to address 0xb4803ea1. A crafted input will lead to a remote denial of service attack.
CVE-2017-10687: In LibSass 3.4.5, there is a heap-based buffer over-read in the function json_mkstream() in sass_context.cpp. A crafted input will lead to a remote denial of service attack.
CVE-2017-12962: There are memory leaks in LibSass 3.4.5 triggered by deeply nested code, such as code with a long sequence of open parenthesis characters, leading to a remote denial of service attack.
CVE-2017-12963: There is an illegal address access in Sass::Eval::operator() in eval.cpp of LibSass 3.4.5, leading to a remote denial of service attack. NOTE: this is similar to CVE-2017-11555 but remains exploitable after the vendor's CVE-2017-11555 fix (available from GitHub after 2017-07-24).
CVE-2017-12964: 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.
CVE-2017-11342: There is an illegal address access in ast.cpp of LibSass 3.4.5. A crafted input will lead to a remote denial of service attack.
CVE-2017-11341: There is a heap based buffer over-read in lexer.hpp of LibSass 3.4.5. A crafted input will lead to a remote denial of service attack.

10 issues skipped by the security teams:

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-2019-18798: LibSass before 3.6.3 allows a heap-based buffer over-read in Sass::weaveParents in ast_sel_weave.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-2019-18799: LibSass before 3.6.3 allows a NULL pointer dereference in Sass::Parser::parseCompoundSelector in parser_selectors.cpp.
CVE-2019-18797: LibSass 3.6.1 has uncontrolled recursion in Sass::Eval::operator()(Sass::Binary_Expression*) in eval.cpp.
CVE-2018-11698: An issue was discovered in LibSass through 3.5.4. An out-of-bounds read of a memory region was found in the function Sass::handle_error which could be leveraged by an attacker to disclose information or manipulated to read from unmapped memory causing a denial of service.
CVE-2018-11697: An issue was discovered in LibSass through 3.5.4. An out-of-bounds read of a memory region was found in the function Sass::Prelexer::exactly() which could be leveraged by an attacker to disclose information or manipulated to read from unmapped memory causing a denial of service.
CVE-2018-11694: An issue was discovered in LibSass through 3.5.4. A NULL pointer dereference was found in the function Sass::Functions::selector_append which could be leveraged by an attacker to cause a denial of service (application crash) or possibly have unspecified other impact.
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).

Please fix them.
