This results in packet drops in the traffic and eventually the PFE crashes. A manual reboot of the PFE will be required to restore the device to original state.\n\nThis issue affects Junos OS:\u00a0\u00a0\n21.2 before\u00a021.2R3-S7,\n21.4 before 21.4R3-S6,\u00a0\n22.1 before 22.1R3-S5, \n22.2 before 22.2R3-S3,\n22.3 before 22.3R3-S2,\n22.4 before 22.4R3,\n23.2 before\u00a023.2R1-S2, 23.2R2.\n\n\n"}, {"lang": "es", "value": "Una restricci\u00f3n inadecuada de operaciones dentro de los l\u00edmites de una vulnerabilidad de b\u00fafer de memoria en el motor de reenv\u00edo de paquetes (PFE) de Juniper Networks Junos OS permite que un atacante no autenticado basado en la red provoque una denegaci\u00f3n de servicio (DoS).
