CVSS: 7.8EPSS: 0%CPEs: 52EXPL: 3CVE-2017-1000366 – Linux Kernel (Debian 9/10 / Ubuntu 14.04.5/16.04.2/17.04 / Fedora 23/24/25) - 'ldso_dynamic Stack Clash' Local Privilege Escalation
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 •

CVSS: 7.8EPSS: 0%CPEs: 22EXPL: 0CVE-2017-17806 – kernel: HMAC implementation does not validate that the underlying cryptographic hash algorithm is unkeyed allowing local attackers to cause denial-of-service
https://notcve.org/view.php?id=CVE-2017-17806
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. La implementación HMAC (crypto/hmac.c) en el kernel de Linux en versiones anteriores a la 4.14.8 no valida que el algoritmo de hash criptográfico subyacente no tenga clave, lo que permite que un atacante local capaz de utilizar la interfaz hash basada en AF_ALG (CONFIG_CRYPTO_USER_API_HASH) y el algoritmo hash basado en SHA-3 (CONFIG_CRYPTO_SHA3) provoque un desbordamiento de búfer de pila de kernel ejecutando una secuencia manipulada de llamadas al sistema para encontrar una inicialización SHA-3 ausente.
