  2. Vulnerabilities (CVE)
  3. CVE-2026-32836
dr_libs dr_flac.h version 0.13.3 and earlier contain an uncontrolled memory allocation vulnerability in drflac__read_and_decode_metadata() that allows attackers to trigger excessive memory allocation by supplying crafted PICTURE metadata blocks. Attackers can exploit attacker-controlled mimeLength and descriptionLength fields to cause denial of service through memory exhaustion when processing FLAC streams with metadata callbacks.

Summary
  • (es) La versión 0.13.3 y anteriores de dr_libs contienen una vulnerabilidad de asignación de memoria incontrolada en drflac__read_and_decode_metadata() que permite a los atacantes activar una asignación de memoria excesiva al proporcionar bloques de metadatos PICTURE manipulados. Los atacantes pueden explotar los campos mimeLength y descriptionLength controlados por el atacante para causar una denegación de servicio a través del agotamiento de la memoria al procesar flujos FLAC con devoluciones de llamada de metadatos.
