Juniper ScreenOS < 6.3.0r20 L2TP DoS (JSA10704)

High Nessus Plugin ID 86610


The remote host is affected by a denial of service vulnerability.


The remote host is running a version of Juniper ScreenOS prior to 6.3.0r20. It is, therefore, affected by a denial of service vulnerability related to the handling of L2TP packets. An unauthenticated, remote attacker can exploit this, via specially crafted L2TP packet, to cause the system to reboot.


Upgrade to Juniper ScreenOS 6.3.0r20 or later.
