Summary

[none]

Details

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.
