CVE-2023-44181 – Junos OS: QFX5k: l2 loop in the overlay impacts the stability in a EVPN/VXLAN environment

https://notcve.org/view.php?id=CVE-2023-44181

An Improperly Implemented Security Check for Standard vulnerability in storm control of Juniper Networks Junos OS QFX5k devices allows packets to be punted to ARP queue causing a l2 loop resulting in a DDOS violations and DDOS syslog. This issue is triggered when Storm control is enabled and ICMPv6 packets are present on device. This issue affects Juniper Networks: Junos OS * All versions prior to 20.2R3-S6 on QFX5k; * 20.3 versions prior to 20.3R3-S5 on QFX5k; * 20.4 versions prior to 20.4R3-S5 on QFX5k; * 21.1 versions prior to 21.1R3-S4 on QFX5k; * 21.2 versions prior to 21.2R3-S3 on QFX5k; * 21.3 versions prior to 21.3R3-S2 on QFX5k; * 21.4 versions prior to 21.4R3 on QFX5k; * 22.1 versions prior to 22.1R3 on QFX5k; * 22.2 versions prior to 22.2R2 on QFX5k. Una verificación de seguridad implementada incorrectamente para una vulnerabilidad estándar en el control de tormentas de los dispositivos Junos OS QFX5k de Juniper Networks permite que los paquetes se envíen a la cola ARP, lo que provoca un bucle l2 que genera violaciones de DDOS y un registro del sistema DDOS. Este problema se activa cuando el control de tormentas está habilitado y hay paquetes ICMPv6 presentes en el dispositivo. Este problema afecta a Juniper Networks: Junos OS * Todas las versiones anteriores a 20.2R3-S6 en QFX5k; * Versiones 20.3 anteriores a 20.3R3-S5 en QFX5k; * Versiones 20.4 anteriores a 20.4R3-S5 en QFX5k; * Versiones 21.1 anteriores a 21.1R3-S4 en QFX5k; * Versiones 21.2 anteriores a 21.2R3-S3 en QFX5k; * Versiones 21.3 anteriores a 21.3R3-S2 en QFX5k; * Versiones 21.4 anteriores a 21.4R3 en QFX5k; * Versiones 22.1 anteriores a 22.1R3 en QFX5k; * Versiones 22.2 anteriores a 22.2R2 en QFX5k. • https://supportportal.juniper.net/JSA73145 https://www.juniper.net/documentation/us/en/software/junos/security-services/topics/task/rate-limiting-storm-control-disabling-cli-els.html • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

CVE-2023-44178 – Junos OS : Stack overflow vulnerability in CLI command processing

https://notcve.org/view.php?id=CVE-2023-44178

A Stack-based Buffer Overflow vulnerability in the CLI command of Juniper Networks Junos OS allows a low privileged attacker to execute a specific CLI commands leading to Denial of Service. Repeated actions by the attacker will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks: Junos OS * All versions prior to 19.1R3-S10; * 19.2 versions prior to 19.2R3-S7; * 19.3 versions prior to 19.3R3-S8; * 19.4 versions prior to 19.4R3-S12; * 20.2 versions prior to 20.2R3-S8; * 20.4 versions prior to 20.4R3-S8; * 21.2 versions prior to 21.2R3-S6; * 21.3 versions prior to 21.3R3-S5; * 21.4 versions prior to 21.4R3-S5; * 22.1 versions prior to 22.1R3-S3; * 22.2 versions prior to 22.2R3-S2; * 22.3 versions prior to 22.3R3-S1; * 22.4 versions prior to 22.4R2-S1; * 23.2 versions prior to 23.2R2.

CVE-2023-44175 – Junos OS and Junos OS Evolved: Receipt of a specific genuine PIM packet causes RPD crash

https://notcve.org/view.php?id=CVE-2023-44175

A Reachable Assertion vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows to send specific genuine PIM packets to the device resulting in rpd to crash causing a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. Note: This issue is not noticed when all the devices in the network are Juniper devices. This issue affects Juniper Networks: Junos OS: * All versions prior to 20.4R3-S7; * 21.2 versions prior to 21.2R3-S5; * 21.3 versions prior to 21.3R3-S4; * 21.4 versions prior to 21.4R3-S4; * 22.1 versions prior to 22.1R3-S4; * 22.2 versions prior to 22.2R3; * 22.3 versions prior to 22.3R3; * 22.4 versions prior to 22.4R3. Junos OS Evolved: * All versions prior to 22.3R3-EVO; * 22.4-EVO versions prior to 22.4R3-EVO; * 23.2-EVO versions prior to 23.2R1-EVO. Una vulnerabilidad de aserción accesible en Routing Protocol Daemon (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite enviar paquetes PIM genuinos específicos al dispositivo, lo que provoca que rpd falle y provoque una Denegación de Servicio (DoS). La recepción y procesamiento continuo de este paquete creará una condición sostenida de Denegación de Servicio (DoS). Nota: Este problema no se detecta cuando todos los dispositivos de la red son dispositivos Juniper. Este problema afecta a Juniper Networks: Junos OS: * Todas las versiones anteriores a 20.4R3-S7; * Versiones 21.2 anteriores a 21.2R3-S5; * Versiones 21.3 anteriores a 21.3R3-S4; * Versiones 21.4 anteriores a 21.4R3-S4; * Versiones 22.1 anteriores a 22.1R3-S4; * Versiones 22.2 anteriores a 22.2R3; * Versiones 22.3 anteriores a 22.3R3; * Versiones 22.4 anteriores a 22.4R3. • https://supportportal.juniper.net/JSA73141 • CWE-617: Reachable Assertion •
