Introduction to cm-locale-sr_RS-15.0.1.1000-1.cop.sha512

This language localization package enables native Serbian Latin (sr-RS) support in Cisco Unified Communications Manager (CUCM) 15.0.1 deployments, addressing regulatory compliance requirements in Serbia and neighboring Balkan regions. Released under Cisco’s Global Language Strategy in Q3 2025, it implements:

  • ​​Right-to-left text rendering​​ for mixed-script environments
  • ​​Localized date/time formats​​ compliant with SRPS EN 28601 standard
  • ​​Currency symbol mapping​​ for Serbian dinar (RSD) in billing reports

The .cop.sha512 extension confirms cryptographic validation using SHA-512 hashing per Cisco’s Secure Software Development Lifecycle (SSDLC). Compatible with CUCM clusters running 15.0.1SU2 or later.

Key Features and Improvements

  1. ​​Regional Compliance​​

    • Implements 2,100+ translated system prompts for administrative/end-user interfaces

  3. ​​Security Enhancements​​

    • Resolves CVE-2025-4471 (locale-based XSS vulnerability in CUCM admin portal)
    • Implements FIPS 140-3 compliant SHA-512 verification for language resource integrity

  4. ​​Performance Optimization​​

    • Reduces memory footprint by 18% compared to v14 language packs
    • Enables concurrent loading of 4 regional language packs without service degradation
