CVE-2026-70653

A flaw was found in libvips. A heap-based buffer read overflow vulnerability exists in the old-style Radiance RLE decoder. A remote attacker could exploit this by providing a specially crafted Radiance image. This could lead to the disclosure of four bytes of adjacent heap data, potentially...

CVE-2026-70654

A flaw was found in libvips, an image processing library. When applications process untrusted uncompressed PPM Portable Pixmap images through unusual custom libvips sources, a heap buffer overflow can occur. This vulnerability, located in the vipssourcereadtomemory function, allows a local attack...

CVE-2026-70652

A flaw was found in libvips, an image processing library. When libvips is built with libultrahdr support, it can incorrectly size an output buffer during the process of enlarging an incoming JPEG to a very large output before encoding a gain map. This undersized allocation can lead to a heap buff...

CVE-2026-70651

A flaw was found in libvips, an image processing library. When libvips is built without libtiff support but with ImageMagick support, an integer overflow can occur while loading a crafted multi-page Tagged Image File Format TIFF image. This overflow, caused by unchecked calculations of image fram...

CVE-2026-69242

A flaw was found in libvips. A crafted many-band TIFF image, when processed by libvips, can bypass scanline validation and trigger an integer overflow. This overflow leads to a heap buffer overflow, allowing an attacker to access arbitrary memory locations with negative offsets. This can result i...
