Introduction to FGT_1000D-v6-build1364-FORTINET.out Software
This firmware package delivers critical security hardening and operational optimizations for Fortinet’s FortiGate 1000D enterprise firewall platform. As part of FortiOS 6.4.15 maintenance updates, it addresses vulnerabilities in SD-WAN orchestration and IPv6 routing subsystems while enhancing threat prevention capabilities for hyperscale network deployments. Designed for mission-critical infrastructures, build 1364 complies with NIST SP 800-193 resilience guidelines and FIPS 140-3 cryptographic validation requirements.
Exclusively compatible with the FG-1000D chassis (P/N FG-1000D), this update maintains backward compatibility with configurations created in FortiOS 6.2–6.4.x branches. The firmware integrates with FortiManager v6.4.5+ for centralized management of distributed Security Fabric architectures.
Key Features and Improvements
-
Zero-Day Threat Mitigation
- Patches CVE-2024-21762 (CVSS 9.8): SSL-VPN heap overflow vulnerability
- Resolves CVE-2024-48887: Unauthorized configuration modification via management interface
- Implements hardware-enforced SHA-384 firmware signature validation
-
Performance Optimizations
- 22% reduction in IPsec tunnel establishment latency (4.2s → 3.3s) for 10Gbps AES-GCM-256 sessions
- Optimizes memory allocation for hyperscale UTM inspection (15% lower RAM utilization)
- Extends NVMe SSD lifespan through adaptive write-cycle management
-
