DSF Parser Memory Corruption in music-metadata

Publication date: 2026-10-08

Last updated on: 2026-10-08

Assigner: GitHub, Inc.

Description
music-metadata is a metadata parser for audio and video media files. Prior to 11.15.0, the DSF parser handles an unrecognized chunk by calling tokenizer.ignore without awaiting the returned promise and without first rejecting a chunk size smaller than the 12-byte chunk header. A crafted DSF input can produce a negative ignore length; with strtok3 10.3.5 or later, the resulting RangeError is detached from the parseBuffer promise and becomes an unhandled rejection under Node.js default behavior. The parse call can appear to resolve before the process crashes, bypassing per-parse try/catch handling. The demonstrated impact is availability loss only and requires the DSF parsing path. This issue is fixed in version 11.15.0.

Executive Summary

This vulnerability affects the music-metadata library, which parses metadata from audio and video files. The issue occurs in the DSF parser when handling unrecognized chunks. It fails to properly await a promise or reject invalid chunk sizes, leading to a negative ignore length. This can cause a RangeError that crashes the process without proper error handling, resulting in availability loss.

Detection Guidance

Detection requires checking the version of music-metadata library in use. Commands like 'npm list music-metadata' or 'find / -name package.json -exec grep -l music-metadata {} \;' can help identify affected installations.

Impact Analysis

If you use the affected music-metadata library (before version 11.15.0) to parse DSF audio files, an attacker could craft a malicious file to crash your application or service. This leads to denial of service, disrupting availability of systems relying on this library for media processing.

Compliance Impact

This vulnerability primarily impacts system availability by causing uncatchable process crashes when parsing malformed DSF files. While it does not directly expose or leak data, compliance risks arise from potential service disruptions that could affect data processing workflows. For GDPR, availability issues may impact data subject rights if systems fail to process requests. For HIPAA, downtime could disrupt access to protected health information, though no data breach is indicated.

Mitigation Strategies

Upgrade music-metadata to version 11.15.0 or later immediately. Use commands like 'npm update music-metadata' or 'yarn upgrade music-metadata' depending on your package manager.
