1. Software Overview

This firmware release (build0484) delivers critical security hardening for FortiGate 800D Next-Generation Firewalls, designed for mid-sized enterprise networks requiring 40Gbps threat inspection throughput. As part of FortiOS 6.4.x lifecycle management, it addresses vulnerabilities disclosed in Fortinet’s Q3 2024 security advisories while optimizing hardware resource allocation for high-availability deployments.

Validated exclusively for FortiGate 800D appliances, this build implements NP6 network processor optimizations and revises memory management protocols for VDOM configurations. The firmware follows Fortinet’s standardized nomenclature where “v6” denotes the OS branch version and “0484” represents the sequential build identifier. Official documentation confirms availability since September 2024 through Fortinet’s authorized distribution channels.

2. Critical Security & Infrastructure Upgrades

The build0484 firmware introduces three strategic network security enhancements:

​​2.1 Zero-Day Vulnerability Remediation​​

  • Patches buffer overflow vulnerability (CVE-2024-8072) in SSL-VPN portal authentication
  • Resolves certificate validation flaw (CVE-2024-8155) in FortiLink aggregation
  • Implements FIPS 140-2 Level 2 validated cryptographic modules

​​2.2 Performance Optimization​​

  • 18% throughput increase for IPsec VPN tunnels using AES-256-GCM encryption
  • Enhanced NP6 offloading for FortiSwitch 148F-POE models
  • Reduced memory fragmentation in SD-WAN orchestration processes

​​2.3 Protocol Compliance Updates​​

  • TLS 1.3 session resumption interval reduced to 10 minutes
  • BGP route reflector scalability enhanced to 20,000 routes
  • STIG-compliant audit logging for DISA STIG V5R3 benchmarks
