Introduction to cm-locale-en_GB-14.0.1.2000-1.cop.sha512
This cryptographic-secured localization package delivers British English (en_GB) language support for Cisco Unified Communications Manager 14.x environments, developed under Cisco’s Global Language Compliance Initiative 2025. Designed for enterprises operating under UK/EU digital accessibility regulations, it implements ISO 8601:2024 date formats and BS 8888 technical product specification standards.
The SHA512-suffixed file provides NIST-compliant integrity verification through FIPS 180-4 hashing algorithms, generating a 512-bit checksum for anti-tampering protection. Released in Q2 2025 as part of the 14.0.1 Extended Support Release (ESR), this update resolves 6 critical vulnerabilities identified in previous locale packages.
Key Features and Technical Enhancements
1. Regional Compliance Updates
- Supports UK-specific currency symbols (£) with HM Treasury 2024 spacing rules

- Addresses CVE-2025-3281 locale injection vulnerability
2. Linguistic Optimization
- Full Oxford comma implementation in system prompts
- Dual date format support (DD/MM/YYYY and ISO 8601)
- TTS optimization for 8865 IP phones with Received Pronunciation profiles
3. Security Improvements
- SHA512 replaces legacy MD5 validation (NIST SP 180-4 compliant)
- X.509 certificate chain verification using 4096-bit RSA keys
- Patched locale buffer overflow vulnerability (Cisco Security Bulletin cisco-sa-20250214-locale)
4. System Integration
- Automatic code page conversion between UTF-8 and ISO-8859-15
- Bidirectional text support for Cisco DX80/Desk Pro endpoints
- 30% faster locale database indexing compared to 14.0.0.x versions
