CVE-2026-70654

libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, applications that define unusual custom libvips sources and use them to process untrusted uncompressed PPM images can trigger a max/min error in vips_source_read_to_memory in libvips/iofuncs/source.c. The function uses VIPS_MAX instead of VIPS_MIN when selecting the remaining read size, allowing up to 4032 bytes to be written beyond the allocated heap buffer and causing memory corruption or a process crash. This issue is fixed in version 8.18.3.

These are all security issues fixed in the libvips-devel-8.18.7-1.1 package on the GA media of openSUSE Tumbleweed.

It was discovered that libvips incorrectly handled certain PDF files with a page that defines a width but not a height. An attacker could possibly use this issue to cause libvips to crash, resulting in a denial of service, or obtain sensitive information. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 24.04 LTS. (CVE-2025-59933)

It was discovered that libvips incorrectly determined image dimensions in the vipsload operation, leading to an integer overflow. An attacker could possibly use this issue to cause libvips to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2026-33327)

It was discovered that libvips incorrectly determined image dimensions in the gifload operation on 32-bit systems, leading to an integer overflow.
