Vendor Solution
The following software releases have been updated to resolve this specific issue: Junos OS: 24.4R1-S3, 24.4R2, 25.2R1 and all subsequent releases.
Vendor Workaround
To workaround this issue an administrator must block all traffic from the PFE line card to the Routing Engine (RE) until a fix can be taken. Even while under a persistent DoS attack the RE will continue to be accessible to administrators through non-PFE line card interfaces E.g. Console, FXP0.

| Description | 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. | |
