Description d'origine
La description telle que publiée par la source (souvent en anglais).
libheif is a HEIF and AVIF file format decoder and encoder. Prior to version 1.22.0, Track::init_sample_timing_table() in libheif/sequences/track.cc stores an out-of-bounds chunk index (m_chunks.size()) into m_presentation_timeline when the number of chunks defined in the stco box is less than the number of samples in stsz. A subsequent call to heif_track_get_next_raw_sequence_sample() reads m_chunks[chunk_idx] with that OOB index, causing a heap-buffer-overflow. Version 1.22.0 fixes the issue.
