Upstream source description

gbsplay through 0.0.103 contains a heap out-of-bounds read vulnerability in vgm_open() in gbs.c that walks the VGM command stream without bounds checks. Attackers can supply a crafted VGM file with wait opcodes and no 0x66 terminator to read past the heap buffer and crash the player.
