Vulnerability from fkie_nvd - Published: 2026-04-09 22:16 - Updated: 2026-04-09 22:16

Severity ?

6.5 (Medium) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Summary

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. This issue affects Junos OS Evolved PTX Series: * All versions before 22.4R3-S8-EVO, * from 23.2 before 23.2R2-S5-EVO, * from 23.4 before 23.4R2-EVO, * from 24.2 before 24.2R2-EVO, * from 24.4 before 24.4R2-EVO. This issue affects Junos OS Evolved on QFX5000 Series: * 22.2-EVO version before 22.2R3-S7-EVO, * 22.4-EVO version before 22.4R3-S7-EVO, * 23.2-EVO versions before 23.2R2-S4-EVO, * 23.4-EVO versions before 23.4R2-S5-EVO, * 24.2-EVO versions before 24.2R2-S1-EVO, * 24.4-EVO versions before 24.4R1-S3-EVO, 24.4R2-EVO. This 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 22.1R1-EVO.
