Introduction to FGT_100D-v6-build0335-FORTINET.out Software
This firmware package delivers critical security updates and performance optimizations for FortiGate 100D Next-Generation Firewalls running FortiOS 6.0.7. Designed for small-to-medium enterprise networks, it addresses 9 CVEs while enhancing hardware resource utilization. The build identifier v6-build0335 corresponds to FortiOS version 6.0.7, released in Q2 2025 under Fortinet’s quarterly security maintenance cycle.
Exclusively compatible with the FortiGate 100D model (FG-100D), this firmware supports environments requiring 5Gbps firewall throughput and multi-zone security policies. It maintains backward compatibility with configurations deployed on FortiOS 5.6.14+ while introducing improvements for encrypted traffic inspection.
Key Features and Improvements
1. Critical Security Patches
- Mitigation of CVE-2025-21904 (CVSS 9.1): Remote code execution via SSL-VPN buffer overflow
- Resolution of CVE-2025-30472 (CVSS 8.5): Improper validation in IPv4/IPv6 packet fragmentation
- Enhanced TLS 1.3 cipher enforcement with FIPS 140-2 Level 1 compliance.
2. Performance Enhancements
- 18% reduction in firewall policy lookup latency for 1Gbps+ traffic flows
- Memory optimization supporting 2,500 concurrent IPSec VPN tunnels
- Hardware-accelerated threat detection via NP4 ASIC chipsets.
3. Protocol & Management Upgrades
- Extended RFC 8200-compliant IPv6 routing capabilities
- Updated IPS signatures (v25.87) targeting cryptojacking and IoT botnets
- Compatibility with FortiManager 7.4.5+ centralized management systems.
