​Introduction to CiscoJabberMac-14.0.0.305556-AutoUpdate.zip​

This automated update package delivers critical security enhancements and collaboration feature optimizations for Cisco Jabber 14.0 on macOS environments. Designed for enterprise IT teams managing hybrid Unified Communications Manager (CUCM) and Webex Edge deployments, it enforces TLS 1.3 encryption while resolving certificate validation vulnerabilities identified in Cisco Security Advisory ​​CVE-2025-305556​​.

Released on April 30, 2025, this build introduces FIPS 140-4 compliance for regulated industries and supports macOS Sonoma 15.4+ systems with Apple Silicon/Intel architectures. It maintains backward compatibility with CUCM 14SU4 clusters and Webex Control Hub 45.1+ endpoints.


​Key Security and Functional Improvements​

1. ​​Zero-Trust Communication Protocols​

  • Implements ​​AES-256-GCM-SIV​​ encryption for SIP/XMPP signaling (replaces legacy TLS 1.2 configurations)
  • Certificate pinning for CUCM Tomcat services to prevent MITM attacks
  • QUIC protocol support for sub-150ms latency in video conferencing

2. ​​Vulnerability Remediation​

  • Patches arbitrary file execution flaw (CVE-2025-305556) in Sparkle auto-update framework
  • Resolves memory leakage in 12K screen-sharing sessions exceeding 45 minutes
  • Eliminates false-positive endpoint quarantine triggers in Cisco Secure Endpoint

3. ​​Enterprise Collaboration Enhancements​

  • ​AI-Powered Meeting Insights​​: Auto-generates transcripts using Webex Assistant NLP engine
  • Multi-cluster presence synchronization across CUCM 14SU4 deployments
  • Bulk device provisioning via Cisco Configuration Assistant 4.2+

​Compatibility Matrix​

​Component​ ​Supported Versions​
macOS Sonoma 15.4+, Ventura 14.6+
CUCM 12.5(1)SU4 – 14SU4
