Description Vladimir Vasilev 2026-10-07 10:44:55 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
