An Improper Check for Unusual or Exceptional Conditions vulnerability in telemetry processing of Juniper Networks Junos OS and Junos OS Evolved allows a network-based authenticated attacker to cause the forwarding information base telemetry daemon (fibtd) to crash, leading to a limited Denial of Service.  This issue affects Juniper Networks Junos OS: * from 22.1 before 22.1R1-S2, 22.1R2. Junos OS Evolved:  * from 22.1 before 22.1R1-S2-EVO, 22.1R2-EVO. Una vulnerabilidad de verificación inadecuada de condiciones inusuales o excepcionales en el procesamiento de telemetría de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante autenticado basado en red cause que el daemon de telemetría de la base de información de reenvío (fibtd) se bloquee, lo que lleva a una denegación de servicio limitada. Este problema afecta a Juniper Networks Junos OS: * desde 22.1 antes de 22.1R1-S2, 22.1R2.

An Access of Memory Location After End of Buffer vulnerability in the Layer-2 Control Protocols Daemon (l2cpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker to cause Denial of Service (DoS). On all Junos OS and Junos OS Evolved platforms, when LLDP is enabled on a specific interface, and a malformed LLDP packet is received, l2cpd crashes and restarts. The impact of the l2cpd crash is reinitialization of STP protocols (RSTP, MSTP or VSTP), and MVRP and ERP. Also, if any services depend on LLDP state (like PoE or VoIP device recognition), then these will also be affected. This issue affects: Junos OS: * from 21.4 before 21.4R3-S4,  * from 22.1 before 22.1R3-S4,  * from 22.2 before 22.2R3-S2,  * from 22.3 before 22.3R2-S2, 22.3R3-S1,  * from 22.4 before 22.4R3,  * from 23.2 before 23.2R2. Junos OS Evolved: * from 21.4-EVO before 21.4R3-S5-EVO,  * from 22.1-EVO before 22.1R3-S4-EVO,  * from 22.2-EVO before 22.2R3-S2-EVO,  * from 22.3-EVO before 22.3R2-S2-EVO, 22.3R3-S1-EVO,  * from 22.4-EVO before 22.4R3-EVO,  * from 23.2-EVO before 23.2R2-EVO.

An Incorrect Default Permissions vulnerability in Juniper Networks Junos OS and Junos OS Evolved allows a local, low-privileged attacker to access confidential information on the system. On all Junos OS and Junos OS Evolved platforms, when NETCONF traceoptions are configured, and a super-user performs specific actions via NETCONF, then a low-privileged user can access sensitive information compromising the confidentiality of the system. This issue affects: Junos OS: * all versions before 21.2R3-S7,  * from 21.4 before 21.4R3-S5,  * 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 23.2R1-S2.

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. Una vulnerabilidad de validación de entrada incorrecta en Juniper Tunnel Driver (jtd) y el módulo ICMP de Juniper Networks Junos OS Evolved permite a un atacante no autenticado dentro del dominio administrativo MPLS enviar paquetes específicamente manipulados al motor de enrutamiento (RE) para provocar una denegación de servicio (DoS). ). Cuando el motor de reenvío de paquetes (PFE) recibe paquetes MPLS IPv4 de tránsito específicamente manipulados, estos paquetes se reenvían internamente al RE. La recepción continua de estos paquetes puede crear una condición sostenida de Denegación de Servicio (DoS). • https://supportportal.juniper.net/JSA75728 https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N • CWE-20: Improper Input Validation •
