Affected devices contain a vulnerability that allows an unauthenticated attacker to trigger a denial-of-service condition. The vulnerability can be triggered if a large amount of DCP reset packets are sent to the device. Los dispositivos afectados contienen una vulnerabilidad que permite a un atacante no autentificado desencadenar una condición de denegación de servicio. La vulnerabilidad puede activarse si se envía una gran cantidad de paquetes de restablecimiento de DCP al dispositivo • https://cert-portal.siemens.com/productcert/pdf/ssa-599968.pdf https://us-cert.cisa.gov/ics/advisories/icsa-21-194-03 https://cert-portal.siemens.com/productcert/html/ssa-599968.html • CWE-770: Allocation of Resources Without Limits or Throttling •

A vulnerability has been identified in RUGGEDCOM RM1224 (All versions >= V4.3 and < V6.4), SCALANCE M-800 (All versions >= V4.3 and < V6.4), SCALANCE S615 (All versions >= V4.3 and < V6.4), SCALANCE SC-600 Family (All versions >= V2.0 and < V2.1.3), SCALANCE XB-200 (All versions < V4.1), SCALANCE XC-200 (All versions < V4.1), SCALANCE XF-200BA (All versions < V4.1), SCALANCE XM400 (All versions < V6.2), SCALANCE XP-200 (All versions < V4.1), SCALANCE XR-300WG (All versions < V4.1), SCALANCE XR500 (All versions < V6.2). Affected devices contain a stack-based buffer overflow vulnerability in the handling of STP BPDU frames that could allow a remote attacker to trigger a denial-of-service condition or potentially remote code execution. Successful exploitation requires the passive listening feature of the device to be active. Se ha identificado una vulnerabilidad en RUGGEDCOM RM1224 (Todas las versiones posteriores e incluyendo a V4.3 y anteriores a V6.4), SCALANCE M-800 (Todas las versiones posteriores e incluyendo a V4.3 y anteriores a V6.4), SCALANCE S615 (Todas las versiones posteriores e incluyendo a V4.3 y anteriores a V6.4), SCALANCE SC-600 Family (Todas las versiones posteriores e incluyendo a V2.0 y anteriores a V2.1.3), SCALANCE XB-200 (Todas las versiones anteriores a V4.1), SCALANCE XC-200 (Todas las versiones anteriores a V4.1), SCALANCE XF-200BA (Todas las versiones anteriores a V4.1), SCALANCE XM400 (Todas las versiones anteriores a V6.2), SCALANCE XP-200 (Todas las versiones anteriores a V4.1), SCALANCE XR-300WG (Todas las versiones anteriores a V4.1), SCALANCE XR500 (Todas las versiones anteriores a V6.2). Unos dispositivos afectados contienen una vulnerabilidad de desbordamiento de búfer en la región stack de la memoria en el manejo de frames STP BPDU que podría permitir a un atacante remoto desencadenar una condición de denegación de servicio o una ejecución de código potencialmente remoto. • https://cert-portal.siemens.com/productcert/pdf/ssa-979775.pdf https://us-cert.cisa.gov/ics/advisories/icsa-21-068-03 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2019-13946
Profinet-IO (PNIO) stack versions prior V06.00 do not properly limit internal resource allocation when multiple legitimate diagnostic package requests are sent to the DCE-RPC interface. This could lead to a denial of service condition due to lack of memory for devices that include a vulnerable version of the stack. The security vulnerability could be exploited by an attacker with network access to an affected device. Successful exploitation requires no system privileges and no user interaction. An attacker could use the vulnerability to compromise the availability of the device. Las versiones de la pila Profinet-IO (PNIO) anteriores a la V06.00 no limitan adecuadamente la asignación de recursos internos cuando se envían múltiples solicitudes legítimas de paquetes de diagnóstico a la interfaz DCE-RPC. Esto podría conducir a una condición de denegación de servicio debido a la falta de memoria para los dispositivos que incluyen una versión vulnerable de la pila. • https://cert-portal.siemens.com/productcert/html/ssa-780073.html https://cert-portal.siemens.com/productcert/pdf/ssa-780073.pdf • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.8EPSS: 1%CPEs: 152EXPL: 0CVE-2018-5391 – The Linux kernel, versions 3.9+, IP implementation is vulnerable to denial of service conditions with low rates of specially modified packets
https://notcve.org/view.php?id=CVE-2018-5391
The Linux kernel, versions 3.9+, is vulnerable to a denial of service attack with low rates of specially modified packets targeting IP fragment re-assembly. An attacker may cause a denial of service condition by sending specially crafted IP fragments. Various vulnerabilities in IP fragmentation have been discovered and fixed over the years. The current vulnerability (CVE-2018-5391) became exploitable in the Linux kernel with the increase of the IP fragment reassembly queue size. El kernel de Linux en versiones a partir de la 3.9 es vulnerable a un ataque de denegación de servicio (DoS) con tasas bajas de paquetes especialmente modificados que apuntan hacia el reensamblado de fragmentos de IP. • http://www.arubanetworks.com/assets/alert/ARUBA-PSA-2018-004.txt http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20200115-01-linux-en http://www.openwall.com/lists/oss-security/2019/06/28/2 http://www.openwall.com/lists/oss-security/2019/07/06/3 http://www.openwall.com/lists/oss-security/2019/07/06/4 http://www.securityfocus.com/bid/105108 http://www.securitytracker.com/id/1041476 http://www.securitytracker.com/id/1041637 https://access.redhat.co • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption •
CVSS: 10.0EPSS: 30%CPEs: 54EXPL: 3CVE-2017-14491 – Dnsmasq < 2.78 - 2-byte Heap Overflow
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 •
