Summary

A vulnerability in the Packet Forwarding Engine (PFE) component of Junos OS by Juniper Networks allows unauthenticated network-based attackers to initiate Denial of Service (DoS) attacks. This occurs when the SRX4600 device receives a high volume of targeted traffic, leading to excessive CPU memory utilization due to flawed internal packet processing. The consequences include significant packet loss and eventual failure of the PFE, necessitating a manual reboot to restore functionality. Multiple versions of Junos OS are impacted, and users are advised to review their deployments to ensure protection against potential exploitation.

Affected Version(s)

Junos OS SRX4600 21.2 < 21.2R3-S7

Junos OS SRX4600 21.4 < 21.4R3-S6

Junos OS SRX4600 22.1 < 22.1R3-S5
