Technical details

The IMF_Load() function in libmikmod through version 3.3.15 fails to properly validate note indices when the linear-period header flag is set, allowing crafted module files to reference out-of-range sample indices. This leads to heap out-of-bounds reads when the loader dereferences these invalid indices, enabling memory disclosure or application denial of service.
