ECHO-C4CE-3570-7D06 Vulnerability is in libheif's HEIF sequence parser (Box_stsz::parse in libheif/sequences/seq_boxes.cc, plus track.cc / chunk.cc). This sequence / ISOBMFF track parsing was added in v1.20.0; v1.19.8 — the version we ship — has no sequences/ directory and no Box_stsz at all (verified: no such file or symbol in the v1.19.8 source), so the vulnerable code is not present. The GHSA lists "affected >= 1.19.0", but that range is imprecise: the introducing commit 58c21087 is not in the v1.19.8 tag.
