Junos OS: The kernel will crash when certain USB devices are inserted

Summary

An Unexpected Status Code or Return Value vulnerability in the kernel of Juniper Networks Junos OS allows an unauthenticated attacker with physical access to the device to cause a Denial of Service (DoS). When certain USB devices are connected to a USB port of the routing-engine (RE), the kernel will crash leading to a reboot of the device. The device will continue to crash as long as the USB device is connected.
