## Affected

- libgme game-music-emu: through 0.6.5

## Description

Game Music Emu (libgme) through 0.6.5 contains a global out-of-bounds read vulnerability in Classic_Emu::mute_voices_ that allows attackers to crash applications by supplying NSF files whose voice count exceeds the 16-entry voice-type table. Attackers can craft an NSF header with chip_flags 0x3F, opened through gme_open_data or gme_open_file, to read past the static array during loading and cause denial of service.
