libvips: Possible integer overflow when reading multi-page TIFF images via ImageMagick

libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, libvips built without libtiff support but with ImageMagick support can overflow the combined frame height while loading a crafted multi-page TIFF through VipsForeignLoadMagick. The vulnerable calculations in libvips/foreign/magick6load.c and libvips/foreign/magick7load.c multiply the per-page Ysize by n_frames without a checked bound, which can cause a heap buffer over-read and process crash. Most package-manager builds include libtiff and do not use this affected fallback path. This issue is fixed in version 8.18.3.

CWE-680 Integer Overflow to Buffer Overflow

The product performs a calculation to determine how much memory to allocate, but an integer overflow can occur that causes less memory to be allocated than expected, leading to a buffer overflow.
