In NVIDIA Jetson TX1 L4T R32 version branch prior to R32.2, Tegra bootloader contains a vulnerability in nvtboot in which the nvtboot-cpu image is loaded without the load address first being validated, which may lead to code execution, denial of service, or escalation of privileges. En Jetson TX1 L4T rango de versión de R32 anterior a R32.2 de NVIDIA, el cargador de arranque Tegra contiene una vulnerabilidad en nvtboot en la que se carga la imagen nvtboot-cpu sin que la dirección de carga sea comprobada primero, lo que puede conllevar a la ejecución del código, la denegación del servicio o la escalada de privilegios. • http://www.securityfocus.com/bid/109341 https://nvidia.custhelp.com/app/answers/detail/a_id/4804 https://nvidia.custhelp.com/app/answers/detail/a_id/4835 • CWE-20: Improper Input Validation •

Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4. Los sistemas con microprocesadores que emplean la ejecución especulativa y que realizan la ejecución especulativa de lecturas de memoria antes de que se conozcan las direcciones de todas las anteriores escrituras de memoria podrían permitir la divulgación no autorizada de información a un atacante con acceso de usuario local mediante un análisis de canal lateral. Esto también se conoce como Speculative Store Bypass (SSB), Variant 4. An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). • https://www.exploit-db.com/exploits/44695 https://github.com/mmxsrup/CVE-2018-3639 https://github.com/Shuiliusheng/CVE-2018-3639-specter-v4- https://github.com/malindarathnayake/Intel-CVE-2018-3639-Mitigation_RegistryUpdate http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00007.html http://support.lenovo.com/us/en/solutions/LEN-2213 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •

NVIDIA Tegra kernel contains a vulnerability in the CORE DVFS Thermal driver where there is the potential to read or write a buffer using an index or pointer that references a memory location after the end of the buffer, which may lead to a denial of service or possible escalation of privileges. El kernel de NVIDIA Tegra contiene una vulnerabilidad en el controlador CORE DVFS Thermal, donde existe la posibilidad de que se produzca una lectura o escritura de búfer empleando un índice o un puntero que haga referencia a una ubicación en la memoria después del final del búfer, lo que puede conducir a una denegación de servicio (DoS) o a un posible escalado de privilegios. • http://nvidia.custhelp.com/app/answers/detail/a_id/4635 https://nvidia.custhelp.com/app/answers/detail/a_id/4787 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Heap-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DNS response. Un desbordamiento de búfer basado en memoria dinámica (heap) en dnsmasq en versiones anteriores a la 2.78 permite a los atacantes provocar una denegación de servicio (cierre inesperado) o ejecutar código arbitrario utilizando una respuesta DNS manipulada. A heap buffer overflow was found in dnsmasq in the code responsible for building DNS replies. An attacker could send crafted DNS packets to dnsmasq which would cause it to crash or, potentially, execute arbitrary code. Dnsmasq versions prior to 2.78 suffer from a 2-byte heap-based overflow vulnerability. • https://www.exploit-db.com/exploits/42941 https://github.com/skyformat99/dnsmasq-2.4.1-fix-CVE-2017-14491 http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00006.html http://nvidia.custhelp.com/app/answers/detail/a_id/4560 http://nvidia.custhelp.com/a • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
