Multiple apparent security fixes reported in the changelogs for mediainfo ( and libmediainfo ( 21.03:

FFV1: fix crash with some bitstreams parsing
TIFF: fix division by 0
RF64: fix the WAV malformed chunk size test

Several apparent security fixes in the commit log of libmediainfo since last version too:

21bcafaa Fix floating point exception in File_La::FileHeader_Parse (SF#1151)
91461395 Fix floating point exception when parsing mpeg4 files (SF#1131)

Unsure if exploitable further than a DoS.
