Description (CNA)
libheif is a HEIF and AVIF file format decoder and encoder. Versions prior to 1.22.0 crashes in the public C API `heif_image_handle_get_image_tiling()` when a malformed uncompressed HEIF image item has an associated `uncC` property but no associated `ispe` property. In debug builds this trips the `ispe && uncC` assertion in `ImageItem_uncompressed::get_heif_image_tiling()`. In a release/NDEBUG ASan build, the same file causes a null pointer read at address `0xa8`. Version 1.22.0 fixes the issue.
