"value": "An Improper Check or Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos and Junos OS Evolved allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).\n\nAn attacker can send specific traffic to the device, which causes the rpd to crash and restart. Continued receipt of this traffic will result in a sustained DoS condition.\n\nThis issue only affects devices with an EVPN-VPWS instance with IGMP-snooping enabled.\n\nThis issue affects Junos OS: \n * All versions before 20.4R3-S10,\u00a0\n * from 21.4 before 21.4R3-S6,\u00a0\n * from 22.1 before 22.1R3-S5,\u00a0\n * from 22.2 before 22.2R3-S3,\u00a0\n * from 22.3 before 22.3R3-S2,\u00a0\n * from 22.4 before 22.4R3,\u00a0\n * from 23.2 before 23.2R2;\n\n\nJunos OS Evolved: \n * All versions before 20.4R3-S10-EVO,\u00a0\n * from 21.4-EVO before 21.4R3-S6-EVO,\u00a0\n * from 22.1-EVO before 22.1R3-S5-EVO,\u00a0\n * from 22.2-EVO before 22.2R3-S3-EVO,\u00a0\n * from 22.3-EVO before 22.3R3-S2-EVO,\u00a0\n * from 22.4-EVO before 22.4R3-EVO,\u00a0\n * from 23.2-EVO before 23.2R2-EVO."
