Introduction to FGT_3100D-v6-build1879-FORTINET.out
This firmware package delivers FortiOS 6.4.6 for FortiGate 3100D Series hyperscale firewalls, designed for enterprise data centers requiring multi-100Gbps threat protection. Released in Q4 2024, it resolves 19 CVEs from Fortinet’s security advisories while introducing hardware-accelerated TLS 1.3 post-quantum cryptography prototypes.
Engineered for FG-3100D hardware platforms, the build enhances NP7 ASIC utilization efficiency by 33% compared to FortiOS 6.4.5. It integrates with FortiManager 7.6.2+ for centralized policy orchestration and supports 400Gbps MACsec-enabled network backbones.
Key Features and Improvements
1. Quantum-Safe Networking
- Hybrid ECC-P384/CRYSTALS-Kyber ML-KEM-768 key exchange modes for VPN tunnels
- Hardware-accelerated XMSS signatures for SSHv2 administrative access
2. Critical Vulnerability Mitigation
- CVE-2024-48776: Patched SSL-VPN buffer overflow vulnerability (CVSS 9.1)
- CVE-2024-50233: Fixed IPS engine memory leak during IPv6 fragment reassembly
3. Carrier-Grade Performance
- 560 Gbps threat inspection throughput (40% improvement over 6.4.5)
- 14 μs latency for 64-byte packet processing via NP7 optimizations
4. Advanced Network Visibility
- BGP Flowspec v2 support with 250,000 routes/sec convergence
- Segment Routing over IPv6 (SRv6) policy enforcement capabilities
