CVE-2026-48724

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-24, when using an image with mask the Floyd-Steinberg dithering method it will cause a negative heap buffer over-write. This issue has been patched in version 7.1.2-24.

Use ImageMagick to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 200) including PNG, JPEG, GIF, HEIC, TIFF, DPX, EXR, WebP, Postscript, PDF, and SVG. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.
