Introduction to Cisco_FTD_Patch-6.7.0.2-24.sh.REL.tar
This cumulative patch package addresses critical vulnerabilities and operational improvements for Cisco Firepower Threat Defense (FTD) software version 6.7.0.x deployments. Released under Cisco’s quarterly maintenance cycle in Q3 2025, it resolves 17 CVEs while maintaining backward compatibility with Firepower 2100/4100 series appliances and FTDv virtual firewalls. The patch implements FIPS 140-3 validated cryptographic modules for government-regulated environments.
Compatible with both physical and cloud-native deployments, this update enhances TLS 1.3 session handling and optimizes intrusion prevention system (IPS) signature verification workflows. System administrators should prioritize installation for environments processing PCI-DSS 4.0 regulated transactions due to enhanced payment data protection mechanisms.
