CVSS: 8.7EPSS: 0%CPEs: 5EXPL: 0CVE-2024-39529 – Junos OS: SRX Series: If DNS traceoptions are configured in a DGA or tunnel detection scenario specific DNS traffic leads to a PFE crash
https://notcve.org/view.php?id=CVE-2024-39529
A Use of Externally-Controlled Format String vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS). If DNS Domain Generation Algorithm (DGA) detection or tunnel detection, and DNS-filtering traceoptions are configured, and specific valid transit DNS traffic is received this causes a PFE crash and restart, leading to a Denial of Service. This issue affects Junos OS: * All versions before 21.4R3-S6, * 22.2 versions before 22.2R3-S3, * 22.3 versions before 22.3R3-S3, * 22.4 versions before 22.4R3, * 23.2 versions before 23.2R2. • https://supportportal.juniper.net/JSA82988 • CWE-134: Use of Externally-Controlled Format String •

CVSS: 8.7EPSS: 0%CPEs: 6EXPL: 0CVE-2024-39518 – Junos OS: MX240, MX480, MX960 platforms using MPC10E: Memory leak will be observed when subscribed to a specific subscription on Junos Telemetry Interface
https://notcve.org/view.php?id=CVE-2024-39518
A Heap-based Buffer Overflow vulnerability in the telemetry sensor process (sensord) of Juniper Networks Junos OS on MX240, MX480, MX960 platforms using MPC10E causes a steady increase in memory utilization, ultimately leading to a Denial of Service (DoS). When the device is subscribed to a specific subscription on Junos Telemetry Interface, a slow memory leak occurs and eventually all resources are consumed and the device becomes unresponsive. A manual reboot of the Line Card will be required to restore the device to its normal functioning. This issue is only seen when telemetry subscription is active. The Heap memory utilization can be monitored using the following command: > show system processes extensive The following command can be used to monitor the memory utilization of the specific sensor > show system info | match sensord PID NAME MEMORY PEAK MEMORY %CPU THREAD-COUNT CORE-AFFINITY UPTIME 1986 sensord 877.57MB 877.57MB 2 4 0,2-15 7-21:41:32 This issue affects Junos OS: * from 21.2R3-S5 before 21.2R3-S7, * from 21.4R3-S4 before 21.4R3-S6, * from 22.2R3 before 22.2R3-S4, * from 22.3R2 before 22.3R3-S2, * from 22.4R1 before 22.4R3, * from 23.2R1 before 23.2R2. Una vulnerabilidad de desbordamiento de búfer de almacenamiento dinámico en el proceso del sensor de telemetría (sensord) de Juniper Networks Junos OS en plataformas MX240, MX480, MX960 que utilizan MPC10E provoca un aumento constante en la utilización de la memoria, lo que en última instancia conduce a una denegación de servicio (DoS). Cuando el dispositivo está suscrito a una suscripción específica en Junos Telemetry Interface, se produce una pérdida lenta de memoria y, finalmente, se consumen todos los recursos y el dispositivo deja de responder. Será necesario reiniciar manualmente la tarjeta de línea para restaurar el dispositivo a su funcionamiento normal. • https://supportportal.juniper.net/JSA82982 • CWE-122: Heap-based Buffer Overflow •
CVSS: 7.1EPSS: 0%CPEs: 17EXPL: 0CVE-2024-39517 – Junos OS and Junos OS Evolved: Upon processing specific L2 traffic, rpd can hang in devices with EVPN/VXLAN configured
https://notcve.org/view.php?id=CVE-2024-39517
An Improper Check for Unusual or Exceptional Conditions vulnerability in the Layer 2 Address Learning Daemon (l2ald) on Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause Denial of Service (DoS). In an EVPN/VXLAN scenario, when a high amount specific Layer 2 packets are processed by the device, it can cause the Routing Protocol Daemon (rpd) to utilize all CPU resources which causes the device to hang. A manual restart of the rpd is required to restore services. This issue affects both IPv4 and IPv6 implementations. This issue affects Junos OS: All versions earlier than 21.4R3-S7; 22.1 versions earlier than 22.1R3-S5; 22.2 versions earlier than 22.2R3-S3; 22.3 versions earlier than 22.3R3-S3; 22.4 versions earlier than 22.4R3-S2; 23.2 versions earlier than 23.2R2; 23.4 versions earlier than 23.4R1-S1. Junos OS Evolved: All versions earlier than 21.4R3-S7-EVO; 22.1-EVO versions earlier than 22.1R3-S5-EVO; 22.2-EVO versions earlier than 22.2R3-S3-EVO; 22.3-EVO versions earlier than 22.3R3-S3-EVO; 22.4-EVO versions earlier than 22.4R3-S2-EVO; 23.2-EVO versions earlier than 23.2R2-EVO; 23.4-EVO versions earlier than 23.4R1-S1-EVO, 23.4R2-EVO. Una vulnerabilidad de comprobación inadecuada de las condiciones inusuales o excepcionales en el daemon de aprendizaje de direcciones de capa 2 (l2ald) en Juniper Networks Junos OS y Junos OS Evolved permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS). En un escenario EVPN/VXLAN, cuando el dispositivo procesa una gran cantidad de paquetes específicos de Capa 2, puede provocar que el daemon de protocolo de enrutamiento (rpd) utilice todos los recursos de la CPU, lo que provoca que el dispositivo se cuelgue. Es necesario reiniciar manualmente el rpd para restaurar los servicios. • https://supportportal.juniper.net/JSA79175 • CWE-754: Improper Check for Unusual or Exceptional Conditions •
CVSS: 7.1EPSS: 0%CPEs: 14EXPL: 0CVE-2024-39514 – Junos OS and Junos OS Evolved: Receiving specific traffic on devices with EVPN-VPWS with IGMP-snooping enabled will cause the rpd to crash
https://notcve.org/view.php?id=CVE-2024-39514
An Improper Check or Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS). An attacker can send specific traffic to the device, which causes the rpd to crash and restart. Continued receipt of this traffic will result in a sustained DoS condition. This issue only affects devices with an EVPN-VPWS instance with IGMP-snooping enabled. This issue affects Junos OS: * All versions before 20.4R3-S10, * from 21.4 before 21.4R3-S6, * from 22.1 before 22.1R3-S5, * from 22.2 before 22.2R3-S3, * from 22.3 before 22.3R3-S2, * from 22.4 before 22.4R3, * from 23.2 before 23.2R2; Junos OS Evolved: * All versions before 20.4R3-S10-EVO, * from 21.4-EVO before 21.4R3-S6-EVO, * from 22.1-EVO before 22.1R3-S5-EVO, * from 22.2-EVO before 22.2R3-S3-EVO, * from 22.3-EVO before 22.3R3-S2-EVO, * from 22.4-EVO before 22.4R3-EVO, * from 23.2-EVO before 23.2R2-EVO. Una vulnerabilidad de verificación o manejo inadecuado de condiciones excepcionales en el demonio de protocolo de enrutamiento (rpd) de Juniper Networks Junos y Junos OS Evolved permite que un atacante adyacente no autenticado provoque una denegación de servicio (DoS). Un atacante puede enviar tráfico específico al dispositivo, lo que provoca que el rpd falle y se reinicie. La recepción continua de este tráfico dará como resultado una condición DoS sostenida. • https://supportportal.juniper.net/JSA82980 • CWE-703: Improper Check or Handling of Exceptional Conditions •
