Improper Restriction of Operations within the Bounds of a Memory Buffer Vulnerability Affects Junos OS

CVE-2024-30398

What is CVE-2024-30398?

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.
