libvips is a fast image processing library with low memory needs. The EXIF decoder within libvips versions before and including 8.18.1 was not verifying the range of EXIF tag groups before passing data to libexif, leading to a possible null pointer dereference and crash. This has been patched in version 8.18.2.
