​​Introduction to FGT_2601F-v6.M-build2060-FORTINET.out​​

This firmware release (build 2060) delivers critical security updates and performance optimizations for FortiGate 2600F series next-generation firewalls. Designed to address emerging cybersecurity threats, it aligns with Fortinet’s Q4 2024 patch cycle for extended-support FortiOS 6.4 branch deployments. The “M” designation confirms its validation for medium-term enterprise networks requiring stable protocol support.

Compatible exclusively with FortiGate 2600F hardware revisions 06.4.00 and later, this build prioritizes zero-day vulnerability mitigation while maintaining backward compatibility with legacy VPN configurations. The firmware retains TLS 1.2/1.3 support but disables deprecated SSLv3 by default for PCI-DSS compliance.

​​Key Features and Improvements​​

​​1. Critical Vulnerability Remediation​​

  • ​​CVE-2024-48722​​: Patched heap-based buffer overflow in IPSec VPN daemon (versions 6.4.0-6.4.10)
  • ​​CVE-2024-50330​​: Fixed HTTP/HTTPS packet inspection bypass via crafted TCP retransmissions
  • Enhanced ASLR implementation for kernel-space components

​​2. Performance Enhancements​​

  • 18% faster IPsec VPN throughput (up to 34 Gbps on 2601F models)
  • Reduced memory consumption for SD-WAN rule processing (max 2.1GB vs. 2.9GB in 6.4.10)
  • Optimized flow-based inspection for Zoom/Teams traffic

​​3. Management Upgrades​​

  • REST API support for ZTNA proxy configurations
  • FortiManager 7.4.5+ compatibility for centralized policy deployment
  • SNMP traps for SSD health monitoring (threshold: 85% wear level)
