What it is

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).

* All versions before 21.3R3-S1,

* 21.4 versions before 21.4R3,

* 22.1 versions before 22.1R2,
