Juniper ScreenOS 6.3 < 6.3.0r17 DNS Lookup DoS

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

The remote host is running a version of Juniper ScreenOS 6.3 prior to
6.3.0r17. It is, therefore, affected by a denial of service
vulnerability.

A denial of service flaw exists in the built-in DNS lookup client. The
flaw could allow a remote attacker to cause the device to crash or
reboot, and repeated exploitation can result in an extended denial of
service condition.
