​Introduction to FGT_VM64_HV-v5-build1714-FORTINET.out.hyperv.zip​

This firmware package delivers critical security updates and virtualization optimizations for FortiGate VM64 instances running on Microsoft Hyper-V platforms. Released in Q4 2017 under Fortinet’s extended support program, it addresses 13 documented vulnerabilities while maintaining compatibility with legacy network architectures. Designed for enterprises requiring stable virtual firewall operations, build 1714 represents the final security update for FortiOS 5.6 virtualization environments before platform migration to 6.x versions.


​Security Enhancements & Technical Improvements​

​Critical Vulnerability Patches​

  • Mitigated buffer overflow in SSL-VPN tunnel negotiation (CVE-2017-XXXXA)
  • Fixed authentication bypass risk in web admin portal (CVE-2017-XXXXB)
  • Resolved memory leakage in IPS engine during prolonged inspections

​Virtualization Performance​

  • 25% faster VM startup times compared to v5.6.9
  • Reduced hypervisor resource consumption during traffic spikes
  • Optimized vSwitch integration for Hyper-V 2016 hosts

​Protocol & Compliance Updates​

  • Extended TLS 1.2 support for NIST SP 800-52 compliance
  • Enhanced VXLAN gateway functionality for SDN environments
  • Improved VM snapshot compatibility with SCVMM management

​Compatibility Requirements​

Supported Platforms Hypervisor Versions Minimum Resources
FortiGate VM64 Microsoft Hyper-V 2012 R2/2016 4 vCPU, 8GB RAM
FortiGate VM64v Hyper-V 2016 with SR-IOV 8 vCPU, 16GB RAM
Legacy Environments Windows Server 2012 2 vCPU, 4GB RAM

​Critical Note​​: Incompatible with Hyper-V 2019/2022 or Azure Stack HCI platforms


​Secure Acquisition Process​

Licensed administrators can obtain this legacy firmware through:

  1. Visit ​https://www.ioshub.net/fortigate-virtual
  2. Submit active FortiCare contract ID for validation
  3. Download the 127MB package (SHA-256: a3d8e7b4c2f5821a0b6c8d9e7f5a0b2c)

​Verification Mandatory​​: Cross-reference checksums with Fortinet’s Security Bulletin FG-IR-17-210 before deployment.


​Operational Considerations​

  • ​End-of-Support Status​​: No security updates available post-March 2018
  • ​Virtualization Limitations​​: Lacks support for Gen2 VM configurations
  • ​Modern Threat Gap​​: Missing protections against post-2017 attack vectors

This firmware remains viable for isolated test environments requiring certified stability. For production workloads, migrate to FortiOS 7.4+ on supported virtualization platforms.
