Introduction to FGT_80F-v6-build1364-FORTINET.out Software
The FGT_80F-v6-build1364-FORTINET.out firmware delivers FortiOS 6.4.16 for the FortiGate 80F series next-generation firewalls, engineered for branch offices requiring enterprise-grade security with SD-WAN optimization. This build (1364) addresses 9 CVEs disclosed in Q1 2025, including critical vulnerabilities in SSL/TLS session resumption protocols and IPv6 packet fragmentation handling.
Designed exclusively for the FortiGate 80F model (FG-80F), this release enhances encrypted traffic inspection efficiency while maintaining backward compatibility with FortiOS 6.4.x configurations. Officially released on May 8, 2025, it serves as a security maintenance update for organizations requiring extended hardware lifecycle support.
Key Features and Improvements
1. Security Enhancements
- CVE-2025-00472 (CVSS 9.3): Patched buffer overflow vulnerability in deep packet inspection engines during SSL/TLS decryption
- Quantum-Resistant VPN: Implemented hybrid Kyber768/ECDHE-384 encryption for IPsec phase 2 negotiations
- Threat Intelligence Update: Integrated 300+ new IoCs from FortiGuard Labs for advanced cryptojacking detection
2. Performance Optimizations
- NP6Lite ASIC Utilization: Achieved 20% higher threat prevention throughput (5.8 Gbps) compared to build 1300 series
- Memory Optimization: Reduced latency spikes in SD-WAN clusters through dynamic session table allocation
3. Operational Enhancements
- Diagnostic Commands: Introduced 5 new CLI tools for real-time monitoring of SD-WAN path quality metrics
- FortiManager Integration: Enabled JSON-based policy templates for multi-VDOM synchronization with FortiManager 7.6.3+
