CVE-2025-30645
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
A NULL Pointer Dereference vulnerability in the flow daemon (flowd) of Juniper Networks Junos OS on SRX Series allows an attacker causing specific, valid control traffic to be sent out of a Dual-Stack (DS) Lite tunnel to crash the flowd process, resulting in a Denial of Service (DoS). Continuous triggering of specific control traffic will create a sustained Denial of Service (DoS) condition.
On all SRX platforms, when specific, valid control traffic needs to be sent out of a DS-Lite tunnel, a segmentation fault occurs within the flowd process, resulting in a network outage until the flowd process restarts.
This issue affects Junos OS on SRX Series:
- All versions before 21.2R3-S9,
- from 21.4 before 21.4R3-S9,
- from 22.2 before 22.2R3-S5,
- from 22.4 before 22.4R3-S6,
- from 23.2 before 23.2R2-S3,
- from 23.4 before 23.4R2.
