Continuous receipt of these specific TCP packets will lead to a sustained Denial of Service (DoS) condition.\n\n\n\n\n\nThis issue affects:\n\nJuniper Networks Junos OS Evolved\n\n\n\n * All versions earlier than 21.2R3-S7-EVO;\n * 21.3 versions earlier than 21.3R3-S5-EVO ;\n * 21.4 versions earlier than 21.4R3-S5-EVO;\n * 22.1 versions earlier than 22.1R3-S4-EVO;\n * 22.2 versions earlier than 22.2R3-S3-EVO ;\n * 22.3 versions earlier than 22.3R3-EVO;\n * 22.4 versions earlier than 22.4R2-EVO, 22.4R3-EVO.\n\n\n\n\n\n\n"
