libmikmod through 3.3.15 contains a heap out-of-bounds read vulnerability in the IMF_Load() loader that allows attackers to read beyond allocated memory by supplying a crafted IMF module. Attackers can enable the linear-period header flag and map notes to out-of-range samples, causing noteindex indexing far past the heap allocation and crashing applications that load the file.
