Assigner: GitHub_M
Reserved: 11.03.2026 Published: 18.03.2026 Updated: 18.03.2026

music-metadata is a metadata parser for audio and video media files. Prior to version 11.12.3, music-metadata's ASF parser (parseExtensionObject() in lib/asf/AsfParser.ts:112-158) enters an infinite loop when a sub-object inside the ASF Header Extension Object has objectSize = 0. Version 11.12.3 fixes the issue.
