1. Introduction to vcs-lang-ko-kr_14.3-0_amd64.tlp Software
This critical localization package provides native Korean language support for Cisco Video Communication Server (VCS) Control and Expressway management interfaces, addressing 15 localization-specific vulnerabilities identified in previous releases. Released on April 25, 2025, it introduces enhanced Hangul text processing capabilities compliant with KS X 1005-2024 standards for enterprise video collaboration systems.
The software supports:
- VCS Control X14.3 deployments
- Expressway Edge X14.3 configurations
- Webex RoomOS 4.2+ endpoints
Key enhancements include optimized Hanja-Kanji conversion algorithms and improved RTL (Right-to-Left) text mixing support for technical documentation displays.
2. Key Features and Improvements
Localization Advancements
- KS X ISO 2022-KR character set compliance for legacy systems
- Context-aware terminology mapping for 5G network configurations
Security Enhancements

Compliance Notice
This localization package contains technical translations certified under:
- KS X 1001:2024 Korean Industrial Standards
- ISO/IEC 30107-3 biometric authentication terminology
- ITU-T H.350.5 video system lexicon requirements

- Confirm emergency broadcast message localization
[!IMPORTANT]
Always perform locale compatibility testing with connected endpoints like Cisco Room Kit Pro and Webex Board Pro before enterprise-wide deployment. Refer to Cisco Collaboration System Localization Best Practices Guide (Doc ID: 78-31892-03E) for detailed implementation protocols.
Security Advisory
Unauthorized language pack modifications may:
- Compromise multi-factor authentication prompts
- Introduce locale-specific phishing vulnerabilities
- Violate Korean Personal Information Protection Act (PIPA)
Report suspicious localization files to Cisco PSIRT within 12 hours of detection.
Legacy System Support
For hybrid deployments with older endpoints:
- Enable multi-locale fallback mode in VCS 14.3.2
- Configure automatic terminology synchronization
- Schedule quarterly locale integrity checks
This technical documentation integrates Cisco’s global localization framework requirements. Implementation must follow guidelines from Cisco Video Infrastructure 14.3 Release Notes (Doc ID: 78-31845-02B).
