Descriptions
A sustained sequence of different types of normal transit traffic can trigger a high CPU consumption denial of service condition in the Junos OS register and schedule software interrupt handler subsystem when a specific command is issued to the device. This affects one or more threads and conversely one or more running processes running on the system. Once this occurs, the high CPU event(s) affects either or both the forwarding and control plane. As a result of this condition the device can become inaccessible in either or both the control and forwarding plane and stops forwarding traffic until the device is rebooted. The issue will reoccur after reboot upon receiving further transit traffic. Score: 5.7 MEDIUM (CVSS:3.0/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) For network designs utilizing layer 3 forwarding agents or other ARP through layer 3 technologies, the score is slightly higher. Score: 6.5 MEDIUM (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H) If the following entry exists in the RE message logs then this may indicate the issue is present. This entry may or may not appear when this issue occurs. /kernel: Expensive timeout(9) function: Affected releases are Juniper Networks Junos OS: 12.1X46 versions prior to 12.1X46-D50; 12.3X48 versions prior to 12.3X48-D30; 12.3R versions prior to 12.3R12-S7; 14.1 versions prior to 14.1R8-S4, 14.1R9; 14.1X53 versions prior to 14.1X53-D30, 14.1X53-D34; 14.2 versions prior to 14.2R8; 15.1 versions prior to 15.1F6, 15.1R3; 15.1X49 versions prior to 15.1X49-D40; 15.1X53 versions prior to 15.1X53-D31, 15.1X53-D33, 15.1X53-D60. No other Juniper Networks products or platforms are affected by this issue.
Una secuencia prolongada de diferentes tipos de tráfico de tránsito normal pueden provocar una condición de denegación de servicio (DoS) a causa de un consumo elevado de recursos de la CPU en el registro de Junos OS y retrasa el subsistema del manipulador de interrupciones de software cuando un comando específico se envía al dispositivo. Esto afecta a uno o más hilos y a uno o más procesos activos en el sistema. Cuando esto ocurre, el consumo elevado de recursos de CPU afecta al plano de control y/o al direccionamiento. Como resultado de esta condición, el dispositivo se puede volver inaccesible tanto en el plano de control como en el de direccionamiento y puede dejar de direccionar tráfico hasta que el dispositivo se reinicie. Este problema volverá a ocurrir después del reinicio tas recibir más tráfico en tránsito. Valoración: 5.7 MEDIUM (CVSS:3.0/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). Para diseños de red que utilizan agentes de direccionamiento de capa 3 u otros ARP que utilicen tecnologías de capa 3, la valoración es ligeramente superior. Valoración: 6.5 MEDIUM (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). Si la siguiente entrada existe en los logs de mensajes RE entonces puede ser un indicador de que el problema está presente. Esta entrada puede o no aparecer cuando ocurra el problema. /kernel: Expensive timeout(9) function: Las distribuciones afectadas son Juniper Networks Junos OS: 12.1X46 anterior a 12.1X46-D50; 12.3X48 anterior a 12.3X48-D30; 12.3R anterior a 12.3R12-S7; 14.1 anterior a 14.1R8-S4, 14.1R9; 14.1X53 anterior a 14.1X53-D30, 14.1X53-D34; 14.2 anterior a 14.2R8; 15.1 anterior a 15.1F6, 15.1R3; 15.1X49 anterior a 15.1X49-D40; 15.1X53 anterior a 15.1X53-D31, 15.1X53-D33, 15.1X53-D60. No hay ningún otro producto o plataforma de Juniper Networks que se vea afectado por este problema.
