Introduction to asav9-14-4-13.qcow2 Software
The asav9-14-4-13.qcow2 virtual machine image represents Cisco’s maintenance release for the Adaptive Security Virtual Appliance (ASAv) 9.14.x series, specifically optimized for cloud-native security deployments. Released in Q4 2024 as part of Cisco’s extended support cycle, this update resolves 9 CVEs while maintaining backward compatibility with hybrid cloud infrastructure configurations.
Designed for Firepower 4100/4200 Series hardware and major hypervisors (KVM 5.4+, VMware ESXi 7.0 U3+), this QCOW2 package implements critical security patches for SSL/TLS inspection vulnerabilities disclosed in 2024. The 9.14.x branch remains supported until 2026 under Cisco’s long-term service agreement for enterprise networks requiring stable deployment environments.
