> 6.9 MEDIUM · 🧪 PoC

## Beschreibung

libTiMidity through 0.2.8 contains a heap out-of-bounds read vulnerability in the SoundFont loader in src/sndfont.c that uses unvalidated sampleId and instrument generator values as table indices. Attackers can supply a crafted .sf2 file loaded through mid_set_soundfont() to read heap memory out of bounds and crash the application.
