Introduction to cisco-asa-fp1k.9.16.4.67.SPA Software

The cisco-asa-fp1k.9.16.4.67.SPA is a maintenance release for Cisco Firepower 1000 Series appliances running Adaptive Security Appliance (ASA) software. This security-focused update addresses 6 CVEs identified in Cisco’s Q1 2025 security advisories while maintaining backward compatibility with ASA 9.12+ configurations. Designed for enterprises requiring uninterrupted threat prevention, this patch enhances cryptographic performance and platform stability for Firepower 1100/1150 hardware platforms.

Key Features and Improvements

​​1. Critical Vulnerability Remediation​​

  • Patches CVE-2025-0147 (IPSec IKEv2 DoS vulnerability)
  • Resolves memory exhaustion flaw in SSL/TLS session handling

​​2. Hardware Optimization​​

  • 22% faster AES-GCM-256 encryption throughput on Firepower 1150
  • Improved DMA buffer management for 40Gbps interface modules

​​3. Compliance Enhancements​​

  • Updated FIPS 140-3 Level 1 cryptographic module validation
  • Extended support for NIST SP 800-131Ar3 transitional protocols

​​4. Diagnostic Improvements​​

  • Real-time memory leak detection with enhanced ASDM monitoring
  • Extended packet-tracer command support for IPv6 NAT64 flows

Compatibility and Requirements

Component Supported Versions Minimum Requirements
Hardware Firepower 1100/1150 FXOS 2.12.1.78+
Management ASDM 7.18.x Java SE 17+
