{"schemaVersion":3,"id":"CVE-2025-59969","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"A Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in the advanced forwarding toolkit (evo-aftmand/evo-pfemand) of Juniper Networks Junos OS Evolved on PTX Series or QFX5000 Series allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).An attacker sending crafted multicast packets will cause line cards running evo-aftmand/evo-pfemand to crash and restart or non-line card devices to crash and restart. Continued receipt and processing of these packets will sustain the Denial of Service (DoS) condition.\n\nThis issue affects Junos OS Evolved PTX Series:\n\n\n\n  *  All versions before 22.4R3-S8-EVO,\n  *  from 23.2 before 23.2R2-S5-EVO,\n  *  from 23.4 before 23.4R2-EVO,\n  *  from 24.2 before 24.2R2-EVO,\n  *  from 24.4 before 24.4R2-EVO.\n\n\n\n\nThis issue affects Junos OS Evolved on QFX5000 Series:\n\n\n\n  *  22.2-EVO version before 22.2R3-S7-EVO,\n  *  22.4-EVO version before 22.4R3-S7-EVO,\n  *  23.2-EVO versions before 23.2R2-S4-EVO,\n  *  23.4-EVO versions before 23.4R2-S5-EVO,\n  *  24.2-EVO versions before 24.2R2-S1-EVO,\n  *  24.4-EVO versions before 24.4R1-S3-EVO, 24.4R2-EVO.\n\n\nThis issue does not affect Junos OS Evolved on QFX5000 Series versions before: 21.2R2-S1-EVO, 21.2R3-EVO, 21.3R2-EVO, 21.4R1-EVO, and
