AI-suggested
Until a fix is available, avoid opening untrusted or crafted VGM files with gbsplay.
Description
gbsplay versions up to 0.0.103 contain a heap out-of-bounds read vulnerability in the vgm_open() function. This occurs because the function processes VGM command streams without proper bounds checking, allowing a crafted VGM file with specific wait opcodes and missing a 0x66 terminator to cause a read beyond the allocated heap buffer, potentially crashing the player.
