Fortinet FortiGate 1800F any version

A heap-based buffer overflow in the firmware signature verification function of FortiOS versions 7.0.1, 7.0.0, 6.4.0 through 6.4.6, 6.2.0 through 6.2.9, and 6.0.0 through 6.0.13 may allow an attacker to execute arbitrary code via specially crafted installation images.

An insufficient logging vulnerability in FortiGate before 6.4.1 may allow the traffic from an unauthenticated attacker to Fortinet owned IP addresses to go unnoticed.
