GHSA-8CJX-8CPV-M8FR

Vulnerability from github – Published: 2025-10-09 18:30 – Updated: 2025-10-09 18:30

Details

When forwarding-options sampling is enabled, receipt of any traffic destined to the Routing Engine (RE) by the PFE line card leads to an FPC crash and restart, resulting in a Denial of Service (DoS).

Continued receipt and processing of any traffic leading to the RE by the PFE line card will create a sustained Denial of Service (DoS) condition to the PFE line card.

This issue affects Junos OS on SRX4700:

from 24.4 before 24.4R1-S3, 24.4R2

This issue affects IPv4 and IPv6.

Title

Junos OS: SRX4700: When forwarding-options sampling is enabled any traffic destined to the RE will cause the forwarding line card to crash and restart

Summary

A Use of Uninitialized Resource vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on SRX4700 devices allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS). When forwarding-options sampling is enabled, receipt of any traffic destined to the Routing Engine (RE) by the PFE line card leads to an FPC crash and restart, resulting in a Denial of Service (DoS). Continued receipt and processing of any traffic leading to the RE by the PFE line card will create a sustained Denial of Service (DoS) condition to the PFE line card. This issue affects Junos OS on SRX4700: * from 24.4 before 24.4R1-S3, 24.4R2 This issue affects IPv4 and IPv6.
