Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2019-6283)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in Sass::Prelexer::parenthese_scope in prelexer.hpp. A remote attacker can pass specially specially crafted data to the application, trigger out-of-bounds read error and read contents of memory on the system.
2) Uncontrolled Recursion (CVE-ID: CVE-2018-20821)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to uncontrolled recursion in Sass::Parser::parse_css_variable_value in parser.cpp. A remote attacker can trigger the vulnerability and gain access to potentially sensitive information.
3) Out-of-bounds read (CVE-ID: CVE-2018-11698)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in the function Sass::handle_error. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger an out-of-bounds read error and read contents of memory on the system.
4) Improper Certificate Validation (CVE-ID: CVE-2020-24025)
The vulnerability allows a remote attacker to perform MitM attack.
The vulnerability exists due to certificate validation is disabled when requesting binaries even if the user is not specifying an alternative download path. A remote attacker can perform MitM attack and compromise the affected application.
5) Stack-based buffer overflow (CVE-ID: CVE-2018-19838)
The vulnerability allows a remote attacker to cause DoS condition.
The vulnerability exists due to stack-based buffer overflow in functions inside ast.cpp for IMPLEMENT_AST_OPERATORS expansion, as demonstrated by recursive calls involving clone(), cloneChildren(), and copy(). A remote attacker can send a specially crafted sass file, trigger memory corruption and cause the service to crash.
6) NULL pointer dereference (CVE-ID: CVE-2018-11694)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the function Sass::Functions::selector_append. A remote attacker can trick the victim into opening specially crafted data and perform a denial of service (DoS) attack.
7) Use-after-free (CVE-ID: CVE-2018-19827)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
In LibSass 3.5.5, a use-after-free vulnerability exists in the SharedPtr class in SharedPtr.cpp (or SharedPtr.hpp) that may cause a denial of service (application crash) or possibly have unspecified other impact.
8) NULL pointer dereference (CVE-ID: CVE-2018-20190)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the function Sass::Eval::operator()(Sass::Supports_Operator*) in eval.cpp. A remote attacker can trick the victim into opening a specially crafted sass input file and perform a denial of service (DoS) attack.
9) Out-of-bounds read (CVE-ID: CVE-2019-6286)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in Sass::Prelexer::skip_over_scopes in prelexer.hpp when called from Sass::Parser::parse_import(). A remote attacker can pass specially specially crafted data to the application, trigger out-of-bounds read error and read contents of memory on the system.
10) Out-of-bounds read (CVE-ID: CVE-2019-6284)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition in Sass::Prelexer::alternatives in prelexer.hpp. A remote attacker can pass specially specially crafted data to the application, trigger out-of-bounds read error and read contents of memory on the system.
11) Heap-based buffer over-read (CVE-ID: CVE-2018-19839)
The vulnerability allows a remote attacker to cause DoS condition.
The vulnerability exists due to heap-based buffer over-read in the function handle_error in sass_context.cpp. A remote attacker can send a specially crafted sass file, trigger memory corruption and cause the service to crash.
12) NULL pointer dereference (CVE-ID: CVE-2018-19797)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error. A remote attacker can trigger denial of service conditions via a crafted sass input file.
