Introduction to FGT_500D-v6-build1914-FORTINET.out Software
The FGT_500D-v6-build1914-FORTINET.out firmware is a critical security update for Fortinet’s FortiGate 500D enterprise firewall series. Released under FortiOS v6.4.x architecture, this build addresses vulnerabilities while optimizing network stability for large-scale enterprise deployments. Designed for organizations requiring compliance with FIPS 140-2 standards, it enhances threat prevention capabilities and hardware resource allocation for high-density traffic environments.
This firmware is explicitly compatible with FortiGate 500D models (FG-500D) and integrates with FortiOS 6.4.x ecosystems. System administrators managing multi-VPN architectures or hybrid cloud infrastructures will benefit from its optimized IPsec throughput (up to 8 Gbps) and enhanced SSL inspection efficiency.
Key Features and Improvements
1. Critical Security Patches
- CVE-2023-27997 Mitigation: Resolves a heap-based buffer overflow vulnerability in FortiOS SSL-VPN (CVSS 9.8), preventing remote code execution.
- FortiGuard IPS Expansion: Adds 29 new intrusion prevention signatures targeting advanced persistent threats (APTs) and ransomware variants like Cl0p.
2. Performance Enhancements
- Throughput Optimization: Achieves 18 Gbps firewall throughput (22% improvement over v6.2.x) and 4.5 Gbps IPsec VPN performance on FG-500D hardware.
- Memory Efficiency: Reduces RAM consumption by 18% during concurrent DDoS mitigation and deep packet inspection tasks.
3. Protocol & Compliance Updates
- TLS 1.3 Full Support: Enables modern encryption for SSL-VPN and web proxy services, replacing deprecated TLS 1.0/1.1 protocols.
- FIPS 140-2 Validation: Meets federal standards for government and financial sector deployments requiring cryptographic validation.
Compatibility and Requirements
| Supported Hardware | Minimum OS Version | Storage Requirement |
|---|---|---|
| FortiGate 500D (FG-500D) | FortiOS 6.4.0 | 4.2 GB |
| FortiSwitch 548D-FPOE | FortiSwitchOS 6.4.5 | N/A |
| FortiAP 433F | FortiAP 6.4.3 | Not Applicable |
Critical Compatibility Notes:
- Incompatible with FortiGate 500E/400D models due to NP6 ASIC architecture differences.
- Requires firmware rollback protection disabled when downgrading from v7.x configurations.
