CVSS: 6.9EPSS: 0%CPEs: 6EXPL: 0CVE-2024-39553 – Junos OS Evolved: Receipt of arbitrary data when sampling service is enabled, leads to partial Denial of Service (DoS).
https://notcve.org/view.php?id=CVE-2024-39553
An Exposure of Resource to Wrong Sphere vulnerability in the sampling service of Juniper Networks Junos OS Evolved allows an unauthenticated network-based attacker to send arbitrary data to the device, which leads msvcsd process to crash with limited availability impacting Denial of Service (DoS) and allows unauthorized network access to the device, potentially impacting system integrity. This issue only happens when inline jflow is configured. This does not impact any forwarding traffic. • https://supportportal.juniper.net/JSA79101 • CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 8.7EPSS: 0%CPEs: 18EXPL: 0CVE-2024-39552 – Junos OS and Junos OS Evolved: Malformed BGP UPDATE causes RPD crash
https://notcve.org/view.php?id=CVE-2024-39552
An Improper Handling of Exceptional Conditions vulnerability in the routing protocol daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows a network based, unauthenticated attacker to cause the RPD process to crash leading to a Denial of Service (DoS). When a malformed BGP UPDATE packet is received over an established BGP session, RPD crashes and restarts. Continuous receipt of the malformed BGP UPDATE messages will create a sustained Denial of Service (DoS) condition for impacted devices. This issue affects eBGP and iBGP, in both IPv4 and IPv6 implementations. • https://supportportal.juniper.net/JSA75726 • CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 8.7EPSS: 0%CPEs: 9EXPL: 0CVE-2024-39551 – Junos OS: SRX Series and MX Series with SPC3 and MS-MPC/MIC: Receipt of specific packets in H.323 ALG causes traffic drop
https://notcve.org/view.php?id=CVE-2024-39551
An Uncontrolled Resource Consumption vulnerability in the H.323 ALG (Application Layer Gateway) of Juniper Networks Junos OS on SRX Series and MX Series with SPC3 and MS-MPC/MIC, allows an unauthenticated network-based attacker to send specific packets causing traffic loss leading to Denial of Service (DoS). Continued receipt and processing of these specific packets will sustain the Denial of Service condition. The memory usage can be monitored using the below command. user@host> show usp memory segment sha data objcache jsf This issue affects SRX Series and MX Series with SPC3 and MS-MPC/MIC: * 20.4 before 20.4R3-S10, * 21.2 before 21.2R3-S6, * 21.3 before 21.3R3-S5, * 21.4 before 21.4R3-S6, * 22.1 before 22.1R3-S4, * 22.2 before 22.2R3-S2, * 22.3 before 22.3R3-S1, * 22.4 before 22.4R3, * 23.2 before 23.2R2. Una vulnerabilidad de consumo de recursos no controlado en H.323 ALG (Application Layer Gateway) de Juniper Networks Junos OS en las series SRX y MX con SPC3 y MS-MPC/MIC, permite que un atacante basado en red no autenticado envíe paquetes específicos que causen pérdida de tráfico. lo que lleva a una denegación de servicio (DoS). La recepción y el procesamiento continuo de estos paquetes específicos mantendrán la condición de Denegación de Servicio. • https://supportportal.juniper.net/JSA83013 • CWE-400: Uncontrolled Resource Consumption •
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. • https://supportportal.juniper.net/JSA83012 • CWE-401: Missing Release of Memory after Effective Lifetime •
