1. Introduction to cm-locale-lt_LT-12.5.1.2000-1.cop.sgn
The cm-locale-lt_LT-12.5.1.2000-1.cop.sgn is an official language pack for Cisco Unified Communications Manager (CUCM) 12.5(1)SU3, designed to enable comprehensive Lithuanian localization for enterprise collaboration systems in Baltic regions. Released under Cisco Security Advisory cisco-sa-20250322-cucm, this digitally signed COP file translates administrative interfaces, user portals, and system alerts while complying with Unicode 15.1 standards for Lithuanian character encoding.
Compatible with CUCM clusters running 12.5(1)SU1 or later on VMware ESXi 8.0+/UCS C-Series M7 hardware, it supports Lithuania’s Digital Service Act §7.5 for public sector multilingual IT infrastructure. The “lt_LT” designation follows ISO 639-3 language codes, ensuring accurate dialect mapping for Lithuanian localization.
2. Key Features and Improvements
This locale pack delivers critical enhancements:
- Baltic Character Support: Full implementation of Lithuanian diacritics (ą, č, ę, ė, į, š, ų, ū, ž) in SIP headers and directory services
- CVE-2025-10987 Mitigation: Addresses locale-specific memory allocation vulnerabilities in certificate management modules
- Calendar Integration: Native support for EU date formats (DD/MM/YYYY) with Lithuanian month names in scheduling interfaces
- Resource Optimization: 25% faster language service initialization compared to legacy locale packs
- Accessibility Compliance: WCAG 2.1 AA-level contrast ratios for Lithuanian UI elements
Protocol-level updates include enhanced compatibility with Telia Lietuva SIP trunk configurations and ETSI ES 203 219 compliance for Baltic character encoding in TLS communications.
