Introduction to FGT_80E-v6-build1364-FORTINET.out Software
This firmware update delivers critical security hardening and operational optimizations for Fortinet’s FortiGate 80E next-generation firewall platform. As part of FortiOS 6.4.15 maintenance updates, it addresses vulnerabilities in SSL inspection subsystems while enhancing threat prevention capabilities for small-to-medium enterprise networks. Designed for organizations requiring integrated security and network performance, build 1364 implements NIST SP 800-193 resilience guidelines and maintains FIPS 140-2 cryptographic validation.
Exclusively compatible with the FG-80E hardware model (P/N FG-80E), this update supports configurations from FortiOS 6.2–6.4.x branches. The firmware integrates with FortiManager v6.4.5+ for centralized management of Security Fabric architectures, particularly optimized for environments requiring simultaneous UTM inspection and VPN connectivity.
Key Features and Improvements
-
Critical Vulnerability Mitigation
- Patches CVE-2024-21762 (CVSS 9.8): SSL-VPN heap overflow vulnerability affecting all 6.4.x branch devices
- Resolves CVE-2024-48887: Unauthorized configuration modification via management interfaces
- Implements hardware-enforced SHA-384 firmware signature validation chain
-
Performance Enhancements
- 18% reduction in IPsec tunnel establishment latency (3.2s → 2.6s) for AES-256-GCM encrypted sessions
- Optimizes memory allocation for UTM inspection processes (10% lower RAM utilization)
- Improves SSL inspection throughput by 12% for 1Gbps network loads
-
Protocol & Compliance Updates
- Adds RFC 8900 compliance for IPv6 segment routing validation
- Enables TLS 1.3 hardware acceleration on NP6lite security processors
- Updates FIPS 140-2 validation to CMVP certificate #4831 (valid through 2025 Q3)
