ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 6.9.13-28 and 7.1.2-2 for ImageMagick's 32-bit build, a 32-bit integer overflow in the BMP encoder’s scanline-stride computation collapses bytes_per_line (stride) to a tiny value while the per-row writer still emits 3 × width bytes for 24-bpp images. The row base pointer advances using the (overflowed) stride, so the first row immediately writes past its slot and into adjacent heap memory with attacker-controlled bytes. This is a classic, powerful primitive for heap corruption in common auto-convert pipelines. This issue has been patched in versions 6.9.13-28 and 7.1.2-2.

GHSA-mxvv-97wh-cfmm — ImageMagick (WriteBMPImage): 32-bit integer overflow when writing BMP scanline stride → heap buffer overflow

Affected: NuGet: Magick.NET-Q16-AnyCPU, NuGet: Magick.NET-Q16-HDRI-AnyCPU, NuGet: Magick.NET-Q16-HDRI-x86, NuGet: Magick.NET-Q16-x86, NuGet: Magick.NET-Q8-AnyCPU, NuGet: Magick.NET-Q8-x86

## Summary

A 32-bit integer overflow in the BMP encoder’s scanline-stride computation collapses `bytes_per_line` (stride) to a tiny value while the per-row writer still emits `3 × width` bytes for 24-bpp images. The row base pointer advances using the (overflowed) stride, so the first row immediately writes past its slot and into adjacent heap memory with attacker-controlled bytes. This is a classic, powerful primitive for heap corruption in common auto-convert pipelines.

- **Impact:** Attacker-controlled heap out-of-bounds (OOB) write during conversion **to BMP**. - **Surface:** Typical upload → normalize/thumbnail → `magick ... out.bmp` workers. - **32-bit:** **Vulnerable** (reproduced with ASan). - **64-bit:** Safe from this specific integer overflow (IOF) by arithmetic, but still add product/size guards. - **Proposed severity:** **Critical 9.8** (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

## Scope & Affected Builds

- **Project:** ImageMagick (BMP writer path, `WriteBMPImage` in `coders/bmp.c`). - **Commit under test:** `3fcd081c0278427fc0e8ac40ef75c0a1537792f7` - **Version string from the run:** `ImageMagick 7.1.2-0 Q8 i686 9bde76f1d:20250712` - **Architecture:** 32-bit i686 (**`sizeof(size_t) == 4`**) with ASan/UBSan. - **Note on other versions:** Any release/branch with the same stride arithmetic and row loop is likely affected on 32-bit.

OESA-2025-2193 — ImageMagick security update

Affected: openEuler:22.03-LTS-SP3: ImageMagick

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. Security Fix(es):

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-1, ImageMagick is vulnerable to heap-buffer overflow read around the handling of images with separate alpha channels when performing image magnification in ReadOneMNGIMage. This can likely be used to leak subsequent memory contents into the output image. This issue has been patched in version 7.1.2-1.(CVE-2025-55004)

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-1, when preparing to transform from Log to sRGB colorspaces, the logmap construction fails to handle cases where the reference-black or reference-white value is larger than 1024. This leads to corrupting memory beyond the end of the allocated logmap buffer. This issue has been patched in version 7.1.2-1.(CVE-2025-55005)
