music-metadata is a metadata parser for audio and video media files. Prior to 11.16.0, the ID3v2 parser trusts the syncsafe tag-size field and allocates the complete tag body before checking whether the input contains the declared bytes. A truncated file containing only an ID3v2 header can request an allocation approaching 268 MiB; the allocation succeeds, the subsequent read reaches end of stream, the EndOfStreamError is caught internally, and the caller receives a normal metadata object. This issue is fixed in version 11.16.0.
