Description

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.
