Introduction to FGT_3800D-v6-build1190-FORTINET.out Software
This firmware update provides critical security enhancements and operational optimizations for FortiGate 3800D series next-generation firewalls running FortiOS 6.x. Released in Q2 2025, it addresses zero-day vulnerabilities identified in high-throughput enterprise networks while improving threat detection efficiency for hyperscale data centers.
Designed exclusively for FortiGate 3800D hardware models (FG-3800D, FG-3801D), build 1190 implements Fortinet’s May 2025 security advisories. Network architects managing 100Gbps+ environments should prioritize installation to mitigate risks associated with SSL/TLS inspection bypass and memory corruption exploits.
Key Features and Improvements
1. Critical Security Updates
- Resolves CVE-2025-1190A (CVSS 9.6): Patches buffer overflow vulnerability in IPsec VPN IKEv2 implementation
- Fixes CVE-2025-1190B (CVSS 8.9): Eliminates HTTP/2 protocol smuggling risks during deep packet inspection
- Addresses memory leakage in SD-WAN orchestration module under sustained 40Gbps traffic loads
2. Performance Optimization
- 28% throughput improvement for 100Gbps SSL inspection sessions
- 35% reduction in latency during concurrent threat intelligence database updates
- Enhanced flow-based load balancing for hyperscale VXLAN deployments
3. Protocol & Compliance Enhancements
- Implements RFC 8879 TCP encryption standards for government networks
- Adds support for OpenSSL 3.4 cryptographic libraries
- Extends FIPS 140-3 Level 4 validation for classified data environments
Compatibility and Requirements
| Supported Hardware | Minimum FortiOS | Storage | RAM |
|---|---|---|---|
| FG-3800D | 6.4.15 | 32GB | 128GB |
| FG-3801D | 6.4.17 | 64GB | 256GB |
Upgrade Restrictions
