https://notcve.org/view.php?id=CVE-2024-21590
An Improper Input Validation vulnerability in Juniper Tunnel Driver (jtd) and ICMP module of Juniper Networks Junos OS Evolved allows an unauthenticated attacker within the MPLS administrative domain to send specifically crafted packets to the Routing Engine (RE) to cause a Denial of Service (DoS). When specifically crafted transit MPLS IPv4 packets are received by the Packet Forwarding Engine (PFE), these packets are internally forwarded to the RE. Continued receipt of these packets may create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS: * All versions before 21.2R3-S8-EVO; * from 21.4-EVO before 21.4R3-S6-EVO; * from 22.2-EVO before 22.2R3-S4-EVO; * from 22.3-EVO before 22.3R3-S3-EVO; * from 22.4-EVO before 22.4R3-EVO; * from 23.2-EVO before 23.2R2-EVO. * from 23.4-EVO before 23.4R1-S1-EVO.

CVSS: 7.5EPSS: 0%CPEs: 40EXPL: 0CVE-2024-21611 – Junos OS and Junos OS Evolved: In a jflow scenario continuous route churn will cause a memory leak and eventually an rpd crash
https://notcve.org/view.php?id=CVE-2024-21611
A Missing Release of Memory after Effective Lifetime vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). In a Juniper Flow Monitoring (jflow) scenario route churn that causes BGP next hops to be updated will cause a slow memory leak and eventually a crash and restart of rpd. Thread level memory utilization for the areas where the leak occurs can be checked using the below command: user@host> show task memory detail | match so_in so_in6 28 32 344450 11022400 344760 11032320 so_in 8 16 1841629 29466064 1841734 29467744 This issue affects: Junos OS * 21.4 versions earlier than 21.4R3; * 22.1 versions earlier than 22.1R3; * 22.2 versions earlier than 22.2R3. Junos OS Evolved * 21.4-EVO versions earlier than 21.4R3-EVO; * 22.1-EVO versions earlier than 22.1R3-EVO; * 22.2-EVO versions earlier than 22.2R3-EVO. This issue does not affect: Juniper Networks Junos OS versions earlier than 21.4R1. Juniper Networks Junos OS Evolved versions earlier than 21.4R1. Una vulnerabilidad de liberación de memoria faltante después de la vida útil efectiva en Routing Protocol Daemon (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante basado en red no autenticado provoque una denegación de servicio (DoS). En un escenario de Juniper Flow Monitoring (jflow), la rotación de rutas que hace que los siguientes saltos de BGP se actualicen provocará una pérdida de memoria lenta y, finalmente, un bloqueo y reinicio de rpd. La utilización de la memoria a nivel de subproceso para las áreas donde se produce la fuga se puede verificar usando el siguiente comando: user@host> show task memory detail | match so_in so_in6 28 32 344450 11022400 344760 11032320 so_in 8 16 1841629 29466064 1841734 29467744.

CVSS: 7.5EPSS: 0%CPEs: 46EXPL: 0CVE-2024-21604 – Junos OS Evolved: A high rate of specific traffic will cause a complete system outage
https://notcve.org/view.php?id=CVE-2024-21604
An Allocation of Resources Without Limits or Throttling vulnerability in the kernel of Juniper Networks Junos OS Evolved allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). If a high rate of specific valid packets are processed by the routing engine (RE) this will lead to a loss of connectivity of the RE with other components of the chassis and thereby a complete and persistent system outage. Please note that a carefully designed lo0 firewall filter will block or limit these packets which should prevent this issue from occurring. The following log messages can be seen when this issue occurs: <host> kernel: nf_conntrack: nf_conntrack: table full, dropping packet This issue affects Juniper Networks Junos OS Evolved: * All versions earlier than 20.4R3-S7-EVO; * 21.2R1-EVO and later versions; * 21.4-EVO versions earlier than 21.4R3-S5-EVO; * 22.1-EVO versions earlier than 22.1R3-S2-EVO; * 22.2-EVO versions earlier than 22.2R3-EVO; * 22.3-EVO versions earlier than 22.3R2-EVO; * 22.4-EVO versions earlier than 22.4R2-EVO. Una vulnerabilidad de asignación de recursos sin límites ni limitación en el kernel de Juniper Networks Junos OS Evolved permite que un atacante no autenticado basado en la red provoque una denegación de servicio (DoS). Si el motor de enrutamiento (RE) procesa una alta tasa de paquetes válidos específicos, esto provocará una pérdida de conectividad del RE con otros componentes del chasis y, por lo tanto, una interrupción completa y persistente del sistema. Tenga en cuenta que un filtro de firewall lo0 cuidadosamente diseñado bloqueará o limitará estos paquetes, lo que debería evitar que ocurra este problema. • https://supportportal.juniper.net/JSA75745 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:L • CWE-770: Allocation of Resources Without Limits or Throttling •
