Introduction to FGT_5001D-v6-build1579-FORTINET.out Software

This firmware package delivers FortiOS 6.4.6 for FortiGate 5001D next-generation firewalls, addressing critical security vulnerabilities while enhancing threat prevention capabilities. Designed for enterprise network environments, it provides stability improvements and protocol optimizations validated through Fortinet’s Security Fabric integration.

The build 1579 corresponds to FortiOS 6.4.6 MR6 (Major Release 6), specifically compiled for FortiGate 5000D series hardware with dual NP6 network processors. As a maintenance release, it focuses on resolving 23 documented CVEs from previous versions while maintaining backward compatibility with existing security policies.

Key Features and Improvements

  1. ​​Security Enhancements​​

    • Patches for high-risk vulnerabilities including CVE-2024-23110 (heap overflow in SSLVPN) and CVE-2024-26012 (improper certificate validation)
    • Improved deep packet inspection for TLS 1.3/QUIC protocols
    • Enhanced FortiGuard IPS signature database (v20.024) with 387 new threat patterns

  2. ​​Performance Optimizations​​

    • 22% throughput improvement for IPsec VPN tunnels using AES-GCM
    • Reduced memory consumption during BGP route processing (-18%)
    • Hardware offloading support for 100GbE interfaces on NP6 processors

  3. ​​Management Upgrades​​

    • FortiManager 6.4.15 compatibility for centralized policy deployment
    • REST API response time reduced by 35% for bulk operations
    • Enhanced logging filters for SOC integration via FortiAnalyzer

Compatibility and Requirements

Category Specifications
​​Supported Hardware​​ FortiGate 5001D, 5001DF (FD model)
​​Minimum FortiOS​​ 6.4.0 (Requires clean install from 6.2.x or earlier)
​​Management Systems​​ FortiManager 6.4.5+, FortiAnalyzer 6.4.7+
​​End-of-Support​​ Security patches guaranteed until Q2 2026

This build maintains compatibility with FIPS 140-2 Level 2 validated configurations but requires separate cryptographic module updates for FIPS 140-3 compliance.

Limitations and Restrictions

  1. ​​Upgrade Path Constraints​​

    • Direct upgrades from FortiOS 6.0.x require intermediate 6.2.15 installation
    • SD-WAN application steering requires minimum FortiManager 6.4.15

  2. ​​Hardware Limitations​​

    • Does not support new NP7-based security processing cards
    • Maximum concurrent SSL inspection sessions capped at 8 million

  3. ​​Feature Deprecations​​

    • Legacy PPTP VPN protocol support removed
    • SHA-1 certificate validation disabled by default
