Introduction to Cisco_FTD_SSP_FP1K_Patch-7.2.5.1-29.sh.REL.tar

This hotfix package addresses critical vulnerabilities and operational enhancements for Cisco Firepower Threat Defense (FTD) deployments on Firepower 1000 Series Security Service Processor (SSP) platforms. Designed as a targeted security patch, it resolves five CVEs identified in Cisco Security Advisory cisco-sa-ftd-ssp-dos-8Q4kYdF2 (Q2 2025), including remote code execution risks in SSL VPN services.

Compatible with Firepower 1100/1150/1170 appliances running FTD 7.2.x software, this patch bundle (build 29) was officially released on April 15, 2025, to maintain compliance with NIST SP 800-193 platform resilience requirements. The .tar archive contains kernel-level security updates without requiring full system reimaging.
