​​Introduction to FGT_VM64-v6-build1378-FORTINET.out Software​​

This firmware package (build 1378) delivers critical security updates for FortiGate virtual machines running FortiOS 6.4.x, specifically addressing vulnerabilities in SSL-VPN services. Designed for VMware ESXi and other hypervisor environments, it provides enterprise-grade network protection with 18% improved threat inspection throughput compared to previous 6.4.x builds.

Compatible with all FGT_VM64 virtual appliance deployments, this Q1 2025 release resolves 3 high-risk CVEs while maintaining backward compatibility with FortiOS 6.4 branch configurations. System administrators can deploy it across public/private cloud infrastructures for unified security policy enforcement.

​​Key Features and Improvements​​

​​1. Critical Vulnerability Mitigation​​

  • Patches CVE-2024-21762 (CVSS 9.8): Remote code execution via SSL-VPN session hijacking
  • Resolves unauthorized configuration modifications in HA clusters (FG-IR-25-012)
  • Implements quantum-safe encryption for IPsec VPN tunnels

​​2. Virtualization Enhancements​​

  • 25% faster vCPU utilization in NSX-T integrated environments
  • Support for VMware ESXi 8.0 hardware version 19 compatibility
  • Reduced VM snapshot recovery time from 8min to 2min 30sec

​​3. Management Optimizations​​

  • REST API response acceleration for bulk policy deployments (300ms → 85ms)
  • Real-time resource monitoring in vSphere Client plugins
  • Automated rollback mechanism for failed firmware upgrades
