Descriptions
A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Routing Protocol Daemon (rpd) of Juniper Networks Junos OS, Junos OS Evolved allows a network-based unauthenticated attacker to cause a Denial of Service (DoS). When a BGP flow route with redirect IP extended community is received, and the reachability to the next-hop of the corresponding redirect IP is flapping, the rpd process might crash. Whether the crash occurs depends on the timing of the internally processing of these two events and is outside the attackers control. Please note that this issue also affects Route-Reflectors unless 'routing-options flow firewall-install-disable' is configured. This issue affects: Juniper Networks Junos OS: 18.4 versions prior to 18.4R2-S10, 18.4R3-S10; 19.1 versions prior to 19.1R3-S7; 19.2 versions prior to 19.2R1-S8, 19.2R3-S4; 19.4 versions prior to 19.4R3-S8; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S2; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R2. Juniper Networks Junos OS Evolved: All versions prior to 20.4R2-EVO; 21.1-EVO versions prior to 21.1R2-EVO. This issue does not affect Juniper Networks Junos OS versions prior to 18.4R1.
Una vulnerabilidad de Condición de Carrera de Tiempo de Comprobación Tiempo de Uso (TOCTOU) en el demonio de protocolo de enrutamiento (rpd) de Juniper Networks Junos OS, Junos OS Evolved permite a un atacante no autenticado basado en la red causar una Denegación de Servicio (DoS). Cuando es recibida una ruta de flujo BGP con comunidad extendida de IP de redirección, y la accesibilidad al siguiente salto de la IP de redireccionamiento correspondiente es inestable, el proceso rpd podría bloquearse. El hecho de que sea producido el fallo depende del momento en que son procesados internamente estos dos eventos y está fuera del control de atacantes. Tenga en cuenta que este problema también afecta a los Route-Reflectors a menos que sea configurado "routing-options flow firewall-install-disable". Este problema afecta a: Juniper Networks Junos OS: 18.4 versiones anteriores a 18.4R2-S10, 18.4R3-S10; 19.1 versiones anteriores a 19.1R3-S7; 19.2 versiones anteriores a 19.2R1-S8, 19.2R3-S4; 19.4 versiones anteriores a 19.4R3-S8; 20.2 versiones anteriores a 20.2R3-S3; 20.3 versiones anteriores a 20.3R3-S2; 20.4 versiones anteriores a 20.4R3; 21.1 versiones anteriores a 21.1R2. Juniper Networks Junos OS Evolved: Todas las versiones anteriores a 20.4R2-EVO; versiones 21.1-EVO anteriores a 21.1R2-EVO. Este problema no afecta a Juniper Networks Junos OS versiones anteriores a 18.4R1
