Fortinet FortiOS 5.2.x < 5.2.6 ICMP Redirect Response DoS

This script is Copyright (C) 2016 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 Fortinet FortiOS that is 5.2.x
prior to 5.2.6. It is, therefore, affected by a denial of service
vulnerability due to the processing of ICMP redirect packets before a
session has been created. A remote attacker can exploit this to cause
a kernel panic, resulting in a denial of service condition.
