Descriptions
An Improper Check for Unusual or Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows an adjacent, unauthenticated attacker with an established ISIS adjacency to cause a Denial of Service (DoS). The rpd CPU spikes to 100% after a malformed ISIS TLV has been received which will lead to processing issues of routing updates and in turn traffic impact. This issue affects: Juniper Networks Junos OS 19.3 versions prior to 19.3R3-S4; 19.4 versions prior to 19.4R2-S6, 19.4R3-S6; 20.1 versions prior to 20.1R3-S2; 20.2 versions prior to 20.2R3-S3; 20.3 versions prior to 20.3R3-S1; 20.4 versions prior to 20.4R3; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R2. Juniper Networks Junos OS Evolved All versions prior to 20.4R3-S3-EVO; 21.2 versions prior to 21.2R2-EVO. This issue does not affect Juniper Networks Junos OS versions prior to 19.3R1.
Una vulnerabilidad de Comprobación Inapropiada de Condiciones Inusuales o Excepcionales en el Demonio de Protocolo de Enrutamiento (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite que un atacante adyacente y no autenticado con una adyacencia ISIS establecida cause una Denegación de Servicio (DoS). La CPU de rpd es disparada al 100% tras la recepción de un TLV de ISIS malformado, lo que conlleva a problemas de procesamiento de las actualizaciones de enrutamiento y, a su vez, un impacto en el tráfico. Este problema afecta: Juniper Networks Junos OS 19.3 versiones anteriores a 19.3R3-S4; 19.4 versiones anteriores a 19.4R2-S6, 19.4R3-S6; 20.1 versiones anteriores a 20.1R3-S2; 20.2 versiones anteriores a 20.2R3-S3; 20.3 versiones anteriores a 20.3R3-S1; 20.4 versiones anteriores a 20.4R3; 21.1 versiones anteriores a 21.1R3; 21.2 versiones anteriores a 21.2R2. Juniper Networks Junos OS Evolved Todas las versiones anteriores a 20.4R3-S3-EVO; 21.2 versiones anteriores a 21.2R2-EVO. Este problema no afecta a Juniper Networks Junos OS versiones anteriores a 19.3R1
