Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Slowloris HTTP Denial of Service: An attacker can cause a Denial of Service (DoS) by sending headers very slowly keeping HTTP or HTTPS connections and associated resources alive for a long period of time. Node.js: Todas las versiones anteriores a la 6.15.0, 8.14.0, 10.14.0 y 11.3.0: Denegación de servicio (DoS) HTTP mediante Slowloris. Un atacante puede provocar una denegación de servicio (DoS) enviando cabeceras muy lentamente, manteniendo las conexiones HTTP o HTTPS y los recursos asociados vivos durante un largo período de tiempo. It was found that Node.js HTTP server was vulnerable to a Slowloris type attack. An attacker could make long lived connections by sending bytes very slowly to the server, saturating its resource and possibly resulting in a denial of service. • http://www.securityfocus.com/bid/106043 https://access.redhat.com/errata/RHSA-2019:1821 https://nodejs.org/en/blog/vulnerability/november-2018-security-releases https://security.gentoo.org/glsa/202003-48 https://access.redhat.com/security/cve/CVE-2018-12122 https://bugzilla.redhat.com/show_bug.cgi?id=1661005 • CWE-400: Uncontrolled Resource Consumption •

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 •

https://notcve.org/view.php?id=CVE-2014-8559
The d_walk function in fs/dcache.c in the Linux kernel through 3.17.2 does not properly maintain the semantics of rename_lock, which allows local users to cause a denial of service (deadlock and system hang) via a crafted application. La función d_walk en fs/dcache.c en el kernel de Linux hasta 3.17.2 no mantiene debidamente la semántica de rename_lock, lo que permite a usuarios locales causar una denegación de servicio (bloqueo y cuelgue del sistema) a través de una aplicación manipulada. A flaw was found in the way the Linux kernel's VFS subsystem handled file system locks. A local, unprivileged user could use this flaw to trigger a deadlock in the kernel, causing a denial of service on the system. • http://lists.opensuse.org/opensuse-security-announce/2015-01/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://rhn.redhat.com/errata/RHSA-2015-1976.html http:&# • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2014-3673
The SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (system crash) via a malformed ASCONF chunk, related to net/sctp/sm_make_chunk.c and net/sctp/sm_statefuns.c. La implementación SCTP en el kernel de Linux hasta 3.17.2 permite a atacantes remotos causar una denegación de servicio (caída del sistema) a través de un chunk ASCONF malformado, relacionado con net/sctp/sm_make_chunk.c y net/sctp/sm_statefuns.c. A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled malformed Address Configuration Change Chunks (ASCONF). A remote attacker could use either of these flaws to crash the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=9de7922bc709eee2f609cd01d98aaedc4cf5ea74 http://linux.oracle.com/errata/ELSA-2014-3087.html http://linux.oracle.com/errata/ELSA-2014-3088.html http://linux.oracle.com/errata/ELSA-2014-3089.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html • CWE-20: Improper Input Validation •
