Introduction to FGT_140D-v6-build0528-FORTINET.out

This firmware package delivers critical security updates and network performance enhancements for FortiGate 140D next-generation firewalls operating on FortiOS 6.x architectures. Designed to address emerging cyber threats, build 0528 resolves 9 CVEs identified in previous versions while optimizing SSL-VPN stability and threat detection efficiency.

Compatible exclusively with FortiGate 140D hardware (FG-140D model), the firmware requires 2GB RAM and 32GB storage for seamless operation. Released in Q4 2024 per Fortinet’s lifecycle documentation, it maintains backward compatibility with FortiOS 6.2 features while enabling future migration paths to FortiOS 7.x ecosystems.
