Vulnerability Title
libvips: Possible integer overflow when reading multi-page TIFF images via ImageMagick
Vulnerability Description
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.

libvips 数字错误漏洞
Vulnerability Description
libvips是libvips团队开源的一款图像处理库。 libvips 8.18.3之前版本存在数字错误漏洞,该漏洞源于在加载特制多页TIFF时,计算组合帧高度未检查边界地将每页Ysize乘以n_frames,可能导致堆缓冲区越界读取和进程崩溃。
