"value": "\nAn Improper Neutralization of Equivalent Special Elements vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on PTX Series allows a unauthenticated, adjacent attacker to cause a Denial of Service (DoS).\n\nWhen MPLS packets are meant to be sent to a flexible tunnel interface (FTI) and if the FTI tunnel is down, these will hit the reject NH, due to which the packets get sent to the CPU and cause a host path wedge condition. This will cause the FPC to hang and requires a manual restart to recover.\n\nPlease note that this issue specifically affects PTX1000, PTX3000, PTX5000 with FPC3, PTX10002-60C, and PTX10008/16 with LC110x. Other PTX Series devices and Line Cards (LC) are not affected.\n\nThe following log message can be seen when the issue occurs:\n\nCmerror Op Set: Host Loopback: HOST LOOPBACK WEDGE DETECTED IN PATH ID <id> (URI: /fpc/<fpc>/pfe/<pfe>/cm/<cm>/Host_Loopback/<cm>/HOST_LOOPBACK_MAKE_CMERROR_ID[<id>])\nThis issue affects Juniper Networks Junos OS:\n\n\n\n * All versions earlier than 20.4R3-S8;\n * 21.1 versions earlier than 21.1R3-S4;\n * 21.2 versions earlier than 21.2R3-S6;\n * 21.3 versions earlier than 21.3R3-S3;\n * 21.4 versions earlier than 21.4R3-S5;\n * 22.1 versions earlier than 22.1R2-S2, 22.1R3;\n * 22.2 versions earlier than 22.2R2-S1, 22.2R3.\n\n\n\n\n\n\n"
