NVD Description

Note: Versions mentioned in the description apply only to the upstream wildmidi package and not the wildmidi package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

WildMIDI through 0.5.0 contains a heap out-of-bounds read vulnerability in _WM_ParseNewHmi() in src/f_hmi.c that reads past buffers when handling 0xfe sub-events. Attackers can supply a crafted HMI file placing a 0xfe 0x10 sub-event near the buffer end to read up to four bytes past the allocation, crashing the decoding application.
