"value": "An Improper Check for Unusual or Exceptional Conditions vulnerability in the\u00a0Layer 2 Address Learning Daemon (l2ald) on Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause Denial of Service (DoS).\n\nIn an EVPN/VXLAN scenario, when a high amount specific Layer 2 packets are processed by the device, it can cause the Routing Protocol Daemon (rpd) to utilize all CPU resources which causes the device to hang. A manual restart of the rpd is required to restore services.\n\nThis issue affects both IPv4 and IPv6 implementations.\nThis issue affects\nJunos OS:\nAll versions earlier than\u00a021.4R3-S7;\n22.1\u00a0versions earlier than 22.1R3-S5;\n22.2 versions earlier than\u00a022.2R3-S3;\n22.3 versions earlier than\u00a022.3R3-S3;\n22.4 versions earlier than\u00a022.4R3-S2;\n23.2 versions earlier than\u00a023.2R2;\n23.4 versions earlier than\u00a023.4R1-S1.\n\nJunos OS Evolved:\nAll versions earlier than\u00a021.4R3-S7-EVO;\n22.1-EVO versions earlier than\u00a022.1R3-S5-EVO;\n22.2-EVO versions earlier than\u00a022.2R3-S3-EVO;\n22.3-EVO versions earlier than 22.3R3-S3-EVO;\n22.4-EVO versions earlier than\u00a022.4R3-S2-EVO;\n23.2-EVO versions earlier than\u00a023.2R2-EVO;\n23.4-EVO versions earlier than\u00a023.4R1-S1-EVO, 23.4R2-EVO."

"value": "Una vulnerabilidad de comprobaci\u00f3n inadecuada de las condiciones inusuales o excepcionales en el daemon de aprendizaje de direcciones de capa 2 (l2ald) en Juniper Networks Junos OS y Junos OS Evolved permite que un atacante adyacente no autenticado provoque una denegaci\u00f3n de servicio (DoS). En un escenario EVPN/VXLAN, cuando el dispositivo procesa una gran cantidad de paquetes espec\u00edficos de Capa 2, puede provocar que el daemon de protocolo de enrutamiento (rpd) utilice todos los recursos de la CPU, lo que provoca que el dispositivo se cuelgue. Es necesario reiniciar manualmente el rpd para restaurar los servicios. Este problema afecta tanto a las implementaciones de IPv4 como a las de IPv6. Este problema afecta a Junos OS: todas las versiones anteriores a 21.4R3-S7; Versiones 22.1 anteriores a 22.1R3-S5; Versiones 22.2 anteriores a 22.2R3-S3; Versiones 22.3 anteriores a 22.3R3-S3; Versiones 22.4 anteriores a 22.4R3-S2; Versiones 23.2 anteriores a 23.2R2; Versiones 23.4 anteriores a 23.4R1-S1. Junos OS Evolved: todas las versiones anteriores a 21.4R3-S7-EVO; Versiones 22.1-EVO anteriores a 22.1R3-S5-EVO; Versiones 22.2-EVO anteriores a 22.2R3-S3-EVO; Versiones 22.3-EVO anteriores a 22.3R3-S3-EVO; Versiones 22.4-EVO anteriores a 22.4R3-S2-EVO; Versiones 23.2-EVO anteriores a 23.2R2-EVO; Versiones 23.4-EVO anteriores a 23.4R1-S1-EVO, 23.4R2-EVO."
