Vulnerability in Juniper SRX4700 devices (CVE-2025-59964)
Summary
Vulnerability in Juniper SRX4700 devices (CVE-2025-59964). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
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.
