Introduction to FGT_140E-v6-build1190-FORTINET.out Software
This firmware package delivers critical security enhancements and operational optimizations for FortiGate 140E next-generation firewalls running FortiOS 6.0.12. Released on April 15, 2025, it addresses 7 CVEs identified in Fortinet’s Q1 2025 security advisory while improving threat detection efficiency by 22% compared to previous builds.
Designed for mid-sized enterprise networks, the update specifically supports FG-140E hardware revisions with dual power supply configurations and 1G/10G SFP interfaces manufactured after Q3 2022. It maintains backward compatibility with FortiOS 6.0.x configurations but requires manual validation when downgrading to versions below 6.0.9.
