| Título | strukturag libheif 1.21.2 Out-of-Bounds Read |
|---|
| Descrição | This vulnerability is a sequence–track consistency validation flaw in libheif. A crafted file can declare more samples in stsz/stts than are actually covered by stsc. Track::load fails to reject this inconsistent state, allowing it to propagate. As a result, Track::init_sample_timing_table may compute an out-of-range chunkIdx, and Track_Visual::decode_next_image_sample subsequently dereferences m_chunks[chunkIdx] without proper bounds checking. This leads to a heap out-of-bounds read and a process crash (DoS). |
