CVSS: 7.1EPSS: 0%CPEs: 8EXPL: 0CVE-2024-39550 – Junos OS: MX Series with SPC3 line card: Port flaps causes rtlogd memory leak leading to Denial of Service
https://notcve.org/view.php?id=CVE-2024-39550
A Missing Release of Memory after Effective Lifetime vulnerability in the rtlogd process of Juniper Networks Junos OS on MX Series with SPC3 allows an unauthenticated, adjacent attacker to trigger internal events cause ( which can be done by repeated port flaps) to cause a slow memory leak, ultimately leading to a Denial of Service (DoS). Memory can only be recovered by manually restarting rtlogd process. The memory usage can be monitored using the below command. user@host> show system processes extensive | match rtlog This issue affects Junos OS on MX Series with SPC3 line card: * from 21.2R3 before 21.2R3-S8, * from 21.4R2 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-S1, * from 23.2 before 23.2R2, * from 23.4 before 23.4R2. Una vulnerabilidad de liberación de memoria faltante después de la vida útil efectiva en el proceso rtlogd de Juniper Networks Junos OS en la serie MX con SPC3 permite que un atacante adyacente no autenticado desencadene una causa de eventos internos (que se puede lograr mediante solapas repetidas de puertos) para causar una pérdida de memoria lenta. , lo que en última instancia conduce a una denegación de servicio (DoS). La memoria sólo se puede recuperar reiniciando manualmente el proceso rtlogd. El uso de la memoria se puede monitorear usando el siguiente comando. usuario@host> show system processes extensive | match rtlog Este problema afecta a Junos OS en la serie MX con tarjeta de línea SPC3: * desde 21.2R3 antes de 21.2R3-S8, * desde 21.4R2 antes de 21.4R3-S6, * desde 22.1 antes de 22.1R3-S5, * desde 22.2 antes de 22.2R3 -S3, * de 22.3 antes de 22.3R3-S2, * de 22.4 antes de 22.4R3-S1, * de 23.2 antes de 23.2R2, * de 23.4 antes de 23.4R2. • https://supportportal.juniper.net/JSA83012 • CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 8.7EPSS: 0%CPEs: 18EXPL: 0CVE-2024-39549 – Junos OS and Junos OS Evolved: Receipt of malformed BGP path attributes leads to a memory leak
https://notcve.org/view.php?id=CVE-2024-39549
A Missing Release of Memory after Effective Lifetime vulnerability in the routing process daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an attacker to send a malformed BGP Path attribute update which allocates memory used to log the bad path attribute. This memory is not properly freed in all circumstances, leading to a Denial of Service (DoS). Consumed memory can be freed by manually restarting Routing Protocol Daemon (rpd). Memory utilization could be monitored by: user@host> show system memory or show system monitor memory status This issue affects: Junos OS: * All versions before 21.2R3-S8, * from 21.4 before 21.4R3-S8, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S3, * from 23.2 before 23.2R2-S1, * from 23.4 before 23.4R1-S2, 23.4R2, * from 24.2 before 24.2R2-EVO.

https://notcve.org/view.php?id=CVE-2024-39543
A Buffer Copy without Checking Size of Input vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Juniper Networks Junos OS Evolved allows an unauthenticated, adjacent attacker to send specific RPKI-RTR packets resulting in a crash, creating a Denial of Service (DoS) condition. Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue affects Junos OS: * All versions before 21.2R3-S8, * from 21.4 before 21.4R3-S8, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S2, * from 23.2 before 23.2R2-S1, * from 23.4 before 23.4R2.

https://notcve.org/view.php?id=CVE-2024-39541
An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS). When conflicting information (IP or ISO addresses) about a node is added to the Traffic Engineering (TE) database and then a subsequent operation attempts to process these, rpd will crash and restart. This issue affects: Junos OS: * 22.4 versions before 22.4R3-S1, * 23.2 versions before 23.2R2, * 23.4 versions before 23.4R1-S1, 23.4R2, This issue does not affect Junos OS versions earlier than 22.4R1. Junos OS Evolved: * 22.4-EVO versions before 22.4R3-S2-EVO, * 23.2-EVO versions before 23.2R2-EVO, * 23.4-EVO versions before 23.4R1-S1-EVO, 23.4R2-EVO, This issue does not affect Junos OS Evolved versions earlier than before 22.4R1. • https://supportportal.juniper.net/JSA83001 • CWE-755: Improper Handling of Exceptional Conditions •
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 •
