CVE-2024-47506

Summary

A Deadlock vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).

When a large amount of traffic is processed by ATP Cloud inspection, a deadlock can occur which will result in a PFE crash and restart. Whether the crash occurs, depends on system internal timing that is outside the attackers control.

This issue affects Junos OS on SRX Series:

  • All versions before 21.3R3-S1,
  • 21.4 versions before 21.4R3,
  • 22.1 versions before 22.1R2,
