Descripción
*** Pendiente de traducción *** An Incorrect Initialization of Resource vulnerability in the Internal Device Manager (IDM) of Juniper Networks Junos OS on EX4000 models allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).<br />
<br />
On EX4000 models with 48 ports (EX4000-48T, EX4000-48P, EX4000-48MP) a high volume of traffic destined to the device will cause an FXPC crash and restart, which leads to a complete service outage until the device has automatically restarted.<br />
<br />
<br />
<br />
<br />
The following reboot reason can be seen in the output of &#39;show chassis routing-engine&#39; and as a log message:<br />
<br />
