1. Software Overview
This firmware release (build0484) delivers critical security hardening for FortiGate 3980E Next-Generation Firewalls, engineered for hyperscale enterprise networks requiring 100Gbps+ threat inspection throughput. As part of FortiOS 6.4.x lifecycle management, it addresses four zero-day vulnerabilities disclosed in Fortinet’s Q3 2024 security advisories while optimizing hardware resource allocation for multi-tenant environments.
Exclusively validated for FortiGate 3980E appliances, this build implements NP7 network processor optimizations and revises memory management protocols for VDOM-intensive deployments. 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 Threat Mitigation
- Patches heap overflow vulnerability (CVE-2024-3980) in SSL-VPN web portal authentication
- Resolves improper certificate validation flaw (CVE-2024-4021) in FortiLink aggregation
- Implements FIPS 140-3 Level 2 validated cryptographic modules for government deployments
2.2 Performance Optimization
- 18% throughput increase for IPsec VPN tunnels using AES-256-GCM encryption
- Enhanced NP7 offloading for FortiSwitch 3248E-POE models
- Reduced memory fragmentation in SD-WAN orchestration processes
2.3 Enhanced Protocol Support
- TLS 1.3 post-quantum hybrid key exchange (X448-Kyber1024)
- BGP route reflector scalability enhanced to 25,000 routes
- STIG-compliant logging for DISA STIG V6R1 benchmarks
