Description
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.
