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 •

ntpd in NTP 4.x before 4.2.8p8, when autokey is enabled, allows remote attackers to cause a denial of service (peer-variable clearing and association outage) by sending (1) a spoofed crypto-NAK packet or (2) a packet with an incorrect MAC value at a certain time. ntpd en NTP 4.x en versiones anteriores a 4.2.8p8, cuando está habilitada la autoclave, permite a atacantes remotos provocar una denegación de servicio (limpiando el par variable y corte de asociación) enviando (1) un paquete crypto-NAK manipulado o (2) un paquete con un valor MAC incorrecto en un momento determinado. • http://bugs.ntp.org/3043 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00028.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00040.html http://lists.opensuse.org/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

ntpd in NTP before 4.2.8p8 allows remote attackers to cause a denial of service (daemon crash) via a crypto-NAK packet. NOTE: this vulnerability exists because of an incorrect fix for CVE-2016-1547. ntpd en NTP en versiones anteriores a 4.2.8p8 permite a atacantes remotos provocar una denegación de servicio (caída del demonio) a través de un paquete crypto-NAK.
