CVE-2026-102029
Una vulnerabilidad de desreferencia de puntero NULL en el demonio del protocolo de enrutamiento (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite a un par MSDP configurado sin autenticar o a un emisor PIM adyacente provocar una denegación de servicio mediante una política MSDP o PIM que utilice la expansión de AS-path.
