Introduction to FGT_300E-v6-build0387-FORTINET.out Software
This firmware package delivers FortiOS 6.0.14 for FortiGate 300E series next-generation firewalls, designed to address critical network security vulnerabilities while maintaining operational stability for medium-sized enterprise deployments. As a maintenance release for legacy hardware platforms, it provides extended lifecycle support for organizations requiring long-term infrastructure consistency without major feature upgrades.
Compatible exclusively with FortiGate 300E appliances (FG-300E), the build (v6-build0387) entered controlled release in Q2 2024 following validation against NIST SP 800-193 resilience standards. The update prioritizes backward compatibility with existing security policies while implementing mandatory cryptographic protocol updates.
Key Features and Improvements
1. Critical Security Enhancements
- Mitigated CVE-2024-21762 (CVSS 9.8): Remote code execution vulnerability in SSL-VPN services requiring immediate deployment
- Patched memory corruption flaw in IPS engine during HTTP/2 traffic analysis (FG-IR-24-015)
- Updated FortiGuard threat intelligence feeds with 12,000+ new malware signatures
2. Network Performance Optimization
- 15% improvement in IPsec VPN throughput (6.4 Gbps → 7.3 Gbps) using AES-256-GCM encryption
- Reduced firewall policy processing latency by 18ms for networks with 1,000+ concurrent rules
3. Compliance Updates
- Enforced SHA-256 certificate validation for all management interfaces
- Deprecated TLS 1.0/1.1 protocols in alignment with PCI DSS v4.0 requirements
