CVE-2025-21600

An Out-of-Bounds Read vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, logically adjacent BGP peer sending a specifically malformed BGP packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition. This issue only affects systems configured in either of two ways: * systems with BGP traceoptions enabled * systems with BGP family traffic-engineering (BGP-LS) configured and can be exploited from a directly connected and configured BGP peer. This issue affects iBGP and eBGP with any address family configured, and both IPv4 and IPv6 are affected by this vulnerability. This issue affects: Junos OS: * from 21.4 before 21.4R3-S9, * from 22.2 before 22.2R3-S5, * from 22.3 before 22.3R3-S4, * from 22.4 before 22.4R3-S5, * from 23.2 before 23.2R2-S3, * from 23.4 before 23.4R2-S3, * from 24.2 before 24.2R1-S2, 24.2R2; Junos OS Evolved: * from 21.4-EVO before 21.4R3-S9-EVO, * from 22.2-EVO before 22.2R3-S5-EVO, * from 22.3-EVO before 22.3R3-S4-EVO, * from 22.4-EVO before 22.4R3-S5-EVO, * from 23.2-EVO before 23.2R2-S3-EVO, * from 23.4-EVO before 23.4R2-S2-EVO, * from 24.2-EVO before 24.2R1-S2-EVO, 24.2R2-EVO. This issue does not affect versions of Junos OS prior to 21.3R1. This issue does not affect versions of Junos OS Evolved prior to 21.3R1-EVO. This is a similar, but different vulnerability than the issue reported as CVE-2024-39516.

Summary		(es) Una vulnerabilidad de lectura fuera de los límites en el daemon de protocolo de enrutamiento (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un par BGP no autenticado y lógicamente adyacente envíe un paquete BGP específicamente malformado para provocar que rpd se bloquee y se reinicie, lo que da como resultado una denegación de servicio (DoS). La recepción y el procesamiento continuos de este paquete crearán una condición de denegación de servicio (DoS) sostenida. Este problema solo afecta a los sistemas configurados de una de estas dos maneras: * sistemas con opciones de rastreo de BGP habilitadas * sistemas con ingeniería de tráfico de la familia BGP (BGP-LS) configurada y que se puede explotar desde un par BGP conectado y configurado directamente. Este problema afecta a iBGP y eBGP con cualquier familia de direcciones configurada, y tanto IPv4 como IPv6 se ven afectados por esta vulnerabilidad. Este problema afecta a: Junos OS: * Todas las versiones anteriores a 21.4R3-S9, * desde 22.2 hasta 22.2R3-S5, * desde 22.3 hasta 22.3R3-S4, * desde 22.4 hasta 22.4R3-S5, * desde 23.2 hasta 23.2R2-S3, * desde 23.4 hasta 23.4R2-S3, * desde 24.2 hasta 24.2R1-S2, 24.2R2; Junos OS Evolved: * Todas las versiones anteriores a 21.4R3-S9-EVO, * desde 22.2 hasta 22.2R3-S5-EVO, * desde 22.3 hasta 22.3R3-S4-EVO, * desde 22.4 hasta 22.4R3-S5-EVO, * desde 23.2 hasta 23.2R2-S3-EVO, * desde 23.4 hasta 23.4R2-S2-EVO, * desde 24.2 hasta 24.2R1-S2-EVO, 24.2R2-EVO. Esta es una vulnerabilidad similar, pero diferente, al problema informado como CVE-2024-39516.
