Summary

ValleyBell libvgm through commit a6eed945 contains a heap out-of-bounds read vulnerability in the PCM data-block decompressor caused by an unbounded compression-table index. Attackers can supply a crafted .vgm file with a small type 0x7F table and wider compressed values.

Risk Assessment

This can cause crashes in applications playing VGM files and leak heap memory contents.

Recommendation

Update libvgm to a version containing the fix or restrict processing of untrusted .vgm files.
