Technical details

The MTM_Load() function in libmikmod fails to validate the channel count in MultiTracker files before using it to index into a static array named pat, resulting in a global out-of-bounds read. An attacker can supply a crafted .mtm file with a channel count above 32 to read past the array bounds. This requires only that an application attempts to load the malicious file; no authentication or user interaction beyond file opening is required.
