This issue affects Junos OS 12.3X48, 15.1X49, 17.4, 18.1, 18.2, 18.3, 18.4, 19.1. Affected platforms: SRX Series.
On SRX Series devices, a vulnerability in the key-management-daemon (kmd) daemon of Juniper Networks Junos OS allows an attacker to spoof packets targeted to site-to-site IPSec peers before a security association (SA) is established thereby causing a failure to set up the IPSec channel.
Sustained receipt of these spoofed packets can cause a sustained Denial of Service (DoS) condition.
This issue affects IPv4 and IPv6 implementations.
