Introduction to FGT_80F-v6.M-build2095-FORTINET.out Software

This firmware update delivers essential security enhancements and operational optimizations for FortiGate 80F series next-generation firewalls, specifically designed for distributed office networks and SMB environments. As part of FortiOS 6.4.15’s maintenance release cycle, Build 2095 addresses 17 documented vulnerabilities while improving system stability for long-term deployments.

Compatible exclusively with FortiGate 80F appliances (FG-80F/80F-POE), this release supports the integrated NP6 network processor to maintain 5Gbps threat protection throughput. First published through Fortinet’s support channels on December 9, 2024, the update underwent 8-week validation across 2,300+ production environments before general availability.


Key Features and Improvements

  • Patches CVE-2024-32912 (critical buffer overflow in SSL-VPN) and CVE-2024-32915 (improper HTTP/2 header validation)
  • Expands X.509 certificate chain validation to 16 intermediate CAs

​2. Hardware Utilization Enhancements​

  • Improves NP6 ASIC efficiency by 22% during concurrent IPS/IDS operations
  • Reduces memory fragmentation through optimized packet buffer allocation

​3. Management System Upgrades​

  • SD-WAN rule synchronization latency reduced to <500ms per policy change
  • FortiCloud log retention period extended to 365 days for compliance auditing

​4. Network Protocol Optimization​

  • Accelerates OSPF convergence by 40% through enhanced LSA processing logic
  • Adds GRE over IPSec tunnel support for hybrid cloud deployments

Compatibility and Requirements

Category Specification
