An Improper Validation of Syntactic Correctness of Input vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS).
If an attacker sends high rate of specific ICMP traffic to a device with VXLAN configured, this causes a deadlock of the PFE and results in the device becoming unresponsive. A manual restart will be required to recover the device.
This issue only affects EX4100, EX4400, EX4600, QFX5000 Series devices.
This issue affects:
Juniper Networks Junos OS
* 21.4R3 versions earlier than 21.4R3-S4;
* 22.1R3 versions earlier than 22.1R3-S3;
* 22.2R2 versions earlier than 22.2R3-S1;
