Fortinet FortiOS 5.2.x < 5.2.6 ICMP Redirect Response DoS

high Nessus Plugin ID 89867

Language:

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.

Solution

Upgrade to Fortinet FortiOS version 5.2.6 or later.
