A Use of Externally-Controlled Format String 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).

If DNS Domain Generation Algorithm (DGA) detection or tunnel detection, and DNS-filtering traceoptions are configured, and specific valid transit DNS traffic is received this causes a PFE crash and restart, leading to a Denial of Service.

This issue affects Junos OS:
* All versions before 21.4R3-S6,
* 22.2 versions before 22.2R3-S3,
* 22.3 versions before 22.3R3-S3,
* 22.4 versions before 22.4R3,
* 23.2 versions before 23.2R2.
