Descriptions
An Allocation of Resources Without Limits or Throttling and a Missing Release of Memory after Effective Lifetime vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a locally authenticated low privileged attacker to cause a Denial of Sevice (DoS). In a high-scaled BGP routing environment with rib-sharding enabled, two issues may occur when executing a specific CLI command. One is a memory leak issue with rpd where the leak rate is not constant, and the other is a temporary spike in rpd memory usage during command execution. This issue affects: Juniper Networks Junos OS 19.4 versions prior to 19.4R3-S9; 20.2 versions prior to 20.2R3-S5; 20.3 versions prior to 20.3R3-S2; 20.4 versions prior to 20.4R3-S1; 21.1 versions prior to 21.1R3; 21.2 versions prior to 21.2R1-S2, 21.2R2-S1, 21.2R3; 21.3 versions prior to 21.3R2. Juniper Networks Junos OS Evolved All versions prior to 20.4R3-S1-EVO; 21.1-EVO version 21.1R1-EVO and later versions; 21.2-EVO versions prior to 21.2R1-S2-EVO, 21.2R3-EVO; 21.3-EVO versions prior to 21.3R2-EVO. This issue does not affect Juniper Networks Junos OS versions prior to 19.2R1.
Una vulnerabilidad de Asignación de Recursos sin Límites o Estrangulamiento y una Falta de Liberación de Memoria Después del Tiempo de Vida Efectivo en el demonio de protocolo de enrutamiento (rpd) de Juniper Networks Junos OS y Junos OS Evolved permite a un atacante poco privilegiado autenticado localmente causar una Denegación de Servicio (DoS). En un entorno de enrutamiento BGP de gran escala con rib-sharding habilitado, pueden producirse dos problemas cuando es ejecutado un comando CLI específico. Uno es un problema de pérdida de memoria con rpd donde la tasa de filtrado no es constante, y el otro es un pico temporal en el uso de la memoria rpd durante la ejecución del comando. Este problema afecta a: Juniper Networks Junos OS 19.4 versiones anteriores a 19.4R3-S9; 20.2 versiones anteriores a 20.2R3-S5; 20.3 versiones anteriores a 20.3R3-S2; 20.4 versiones anteriores a 20.4R3-S1; 21.1 versiones anteriores a 21.1R3; 21.2 versiones anteriores a 21.2R1-S2, 21.2R2-S1, 21.2R3; 21.3 versiones anteriores a 21.3R2. Juniper Networks Junos OS Evolved Todas las versiones anteriores a 20.4R3-S1-EVO; 21.1-EVO versión 21.1R1-EVO y versiones posteriores; 21.2-EVO versiones anteriores a 21.2R1-S2-EVO, 21.2R3-EVO; 21.3-EVO versiones anteriores a 21.3R2-EVO. Este problema no afecta a Juniper Networks Junos OS versiones anteriores a 19.2R1
