CVE-2026-107390

Estado: AnalizadaAlta (7.5)—

music-metadata es un analizador de metadatos para archivos multimedia de audio y vídeo. En versiones anteriores a la 11.16.0, el analizador MP4 acepta un tamaño de átomo extendido de 64 bits controlado por el atacante, lo convierte en un Number de JavaScript y utiliza la longitud de carga útil resultante para llamadas readToken específicas del átomo antes de comprobar que el átomo cabe dentro de su padre o de la entrada disponible.

Leer descripción completaMostrar menos

Un archivo diminuto de la familia MP4 puede dirigir una longitud sobredimensionada al análisis de la carga útil de átomos como mvhd, stsd, stsz y date, provocando un intento de asignación de gran tamaño o un fallo del proceso antes de la validación del final de la entrada. Por tanto, las aplicaciones que analizan contenido multimedia no confiable de la familia MP4 pueden sufrir una denegación de servicio. Este problema está corregido en la versión 11.16.0.

      "value": "music-metadata is a metadata parser for audio and video media files. Prior to 11.16.0, the MP4 parser accepts an attacker-controlled 64-bit extended atom size, converts it to a JavaScript Number, and uses the resulting payload length for atom-specific readToken calls before proving that the atom fits within its parent or the available input. A tiny MP4-family file can route an oversized length into payload parsing for atoms including mvhd, stsd, stsz, and date, causing a large allocation attempt or process failure before end-of-input validation. Applications that parse untrusted MP4-family media can therefore be denied service. This issue is fixed in version 11.16.0."
