Sources and claim methodology

Upstream source description

libmikmod before 3.3.14 contains a heap out-of-bounds read vulnerability in the Impulse Tracker loader load_it.c that allows attackers to read adjacent heap memory via oversized patterns. Attackers can supply a crafted IT module with more than 200 pattern rows, causing IT_ConvertTrack() to read past the itpat buffer and crash applications.
