Introduction to FGT_60F-v6-build1112-FORTINET-6.2.4.out
This firmware package (build 1112) delivers critical security patches and stability improvements for FortiGate 60F next-generation firewalls running FortiOS 6.2.4. Designed as a maintenance release, it addresses 12 medium-to-high severity vulnerabilities identified in prior 6.2.x versions while optimizing hardware resource allocation for enterprise-grade threat prevention. Exclusively compatible with FortiGate 60F hardware, this update bridges functionality between legacy deployments and modern security frameworks.
Released in Q4 2021 based on Fortinet’s firmware lifecycle documentation, it serves organizations requiring extended support for configurations incompatible with FortiOS 7.x. The filename follows Fortinet’s standardized structure:
- FGT_60F: Targets 60F series hardware
- v6-build1112: Denotes FortiOS 6.2.4 with build-specific optimizations
- FORTINET-6.2.4: Full OS version identifier.
Key Features and Improvements
Security Enhancements
- Mitigates 7 CVEs affecting SSL-VPN and management interfaces, including buffer overflow risks in HTTP/HTTPS packet processing
- Strengthens XSS protections in web admin portal cookie handling
- Implements stricter ASLR (Address Space Layout Randomization) for kernel-level exploit prevention.
Performance Optimization
- 15% faster IPsec VPN throughput via NP6 ASIC hardware acceleration refinements
- Reduced memory contention in UTM inspection queues (-20% average latency)
- Improved log retention stability for devices without dedicated storage drives.
Operational Improvements
- Extended SD-WAN application steering to 50+ SaaS platforms (Microsoft Teams, Zoom)
- Simplified policy migration from FortiOS 6.0.x configurations
- Resolved GUI rendering delays in policy matrix views with 500+ rules.
