https://notcve.org/view.php?id=CVE-2017-14491
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 •

https://notcve.org/view.php?id=CVE-2017-1000366
glibc contains a vulnerability that allows specially crafted LD_LIBRARY_PATH values to manipulate the heap/stack, causing them to alias, potentially resulting in arbitrary code execution. Please note that additional hardening changes have been made to glibc to prevent manipulation of stack and heap memory but these issues are not directly exploitable, as such they have not been given a CVE. This affects glibc 2.25 and earlier. Glibc contiene una vulnerabilidad que permite que los valores LD_LIBRARY_PATH especialmente creados para manipular la región heap/stack de la memoria, generando entonces un alias, lo que podría conllevar a la ejecución del código arbitrario. Tenga en cuenta que se han realizado cambios de refuerzo adicionales en glibc para evitar la manipulación del stack y heap de la memoria de almacenamiento dinámico, pero estos problemas no se pueden explotar directamente, por lo que no se les ha otorgado un CVE. • https://www.exploit-db.com/exploits/42276 https://www.exploit-db.com/exploits/42274 https://www.exploit-db.com/exploits/42275 http://packetstormsecurity.com/files/154361/Cisco-Device-Hardcoded-Credentials-GNU-glibc-BusyBox.html http://seclists.org/fulldisclosure/2019/Sep/7 http://www.debian.org/security/2017/dsa-3887 http://www.securityfocus.com/bid/99127 http://www.securitytracker.com/id/1038712 https://access.redhat.com/errata/RHSA-2017:1479 https://access.redhat.com/errata/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization.

https://notcve.org/view.php?id=CVE-2017-17805
The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable. El algoritmo de cifrado Salsa20 en el kernel de Linux en versiones anteriores a la 4.14.8 no maneja correctamente las entradas de longitud cero, lo que permite a un atacante local capaz de utilizar la interfaz skcipher basada en AF_ALG (CONFIG_CRYPTO_USER_API_SKCIPHER) provocar una denegación de servicio (liberación de memoria no inicializada y fallo del kernel) o provocar otro impacto no especificado ejecutando una secuencia manipulada de llamadas al sistema que utilizan la API blkcipher_walk. Tanto la implementación genérica (crypto/salsa20_generic.c) como la implementación x86 (arch/x86/crypto/salsa20_glue.c) de Salsa20 eran vulnerables.
