Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The npm package music-metadata, versions before 11.16.0, trusts the size field in ID3v2 tags and allocates a buffer of that size before reading the file, so a crafted MP3, FLAC, DSF or Musepack file with a truncated tag can force a very large allocation (up to about 268 MB from a 10-byte file). An attacker only needs to get such a file parsed, for example by uploading it to a service that uses the library, and the result can be memory exhaustion and denial of service. Upgrade to music-metadata 11.16.0 or later, which is the listed fixed version.
