An Improper Validation of Specified Type of Input vulnerability in the packet forwarding engine (pfe) Juniper Networks Junos OS on SRX5000 Series allows an unauthenticated, network based attacker to cause a Denial of Service (Dos).

When a non-clustered SRX5000 device receives a specifically malformed packet this will cause a flowd crash and restart.

This issue affects Junos OS:

22.1 releases 22.1R1 and later before 22.2R3-S5, 22.3 releases before 22.3R3-S4, 22.4 releases before 22.4R3-S4, 23.2 releases before 23.2R2-S2, 23.4 releases before 23.4R2-S1, 24.2 releases before 24.2R1-S1, 24.2R2.

Please note that the PR does indicate that earlier versions have been fixed as well, but these won't be adversely impacted by this.
