Fortinet FortiOS 5.2.x < 5.2.6 ICMP Redirect Response DoS

High Nessus Plugin ID 89867


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


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.


Upgrade to Fortinet FortiOS version 5.2.6 or later.
