ImageMagick versions prior to 7.1.2-8 are vulnerable to denial-of-service due to unsigned integer underflow and division-by-zero in the CLAHEImage function. When tile width or height is zero, unsigned underflow occurs in pointer arithmetic, leading to out-of-bounds memory access, and division-by-zero causes immediate crashes.

7.1.2-8.","severity":{"version":"3.1","score":4.7,"vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.00369,"percentile":0.3117,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-119","CWE-191","CWE-369"],"published":"2025-10-27T20:00:33Z","modified":"2026-11-03T06:32:52Z","fixes":[{"ecosystem":"Alpine:v3.22","package":"imagemagick","fixed_in":["7.1.2.8-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.23","package":"imagemagick","fixed_in":["7.1.2.8-r0"],"sources":["osv"]},{"ecosystem":"Alpine:v3.24","package":"imagemagick","fixed_in":["7.1.2.8-r0"],"sources":["osv"]},{"ecosystem":"Debian:13","package":"imagemagick","fixed_in":["8:7.1.1.43+dfsg1-1+deb13u4"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"imagemagick","fixed_in":["8:7.1.2.8+dfsg1-1"],"sources":["osv"]},{"ecosystem":"Julia","package":"ImageMagick_jll","fixed_in":["7.1.2011+0"],"sources":["osv"]},{"ecosystem":"openEuler:24.03-LTS-SP1","package":"ImageMagick","fixed_in":["7.1.2.8-1.oe2403sp1"],"sources":["osv"]},{"ecosystem":"openEuler:22.03-LTS-SP3","package":"ImageMagick","fixed_in":["7.1.2.8-1.oe2203sp3"],"sources":["osv"]},{"ecosystem":"openEuler:22.03-LTS-SP4","package":"ImageMagick","fixed_in":["7.1.2.8-1.oe2203sp4"],"sources":["osv"]},{"ecosystem":"openEuler:24.03-LTS","package":"ImageMagick","fixed_in":["7.1.2.8-1.oe2403"],"sources":["osv"]},{"ecosystem":"SUSE:Linux

Unsigned integer underflow → out-of-bounds pointer arithmetic (OOB): when `tile_info.height == 0`, the expression `tile_info.height - 1` (unsigned) wraps to a very large value; using that value in pointer arithmetic yields a huge offset and OOB memory access (leading to memory corruption, SIGSEGV, or resource exhaustion).\n 2. **Division/modulus by zero**: where code performs `... / tile_info.width` or `... % tile_info.height` without re-checking for zero, causing immediate division-by-zero crashes under sanitizers or `abort` at runtime.\n\nBoth behaviors are triggered by the same invalid tile condition (e.g., CLI exact `-clahe 0x0!` or automatic tile derivation `dim \u003e\u003e 3 == 0` for very small images).\n\n* * *\n\n## Details\n\n### **Unsigned underflow(can lea to OOB)**\n\n  - Location: `MagickCore/enhance.c`, around line 609\n\n  - Version tested: 7.1.2-8 (local ASan(undefined). /UBSan build)\n  - Vulnerable code\n    \n    enhance.c: 609\n    \n    ```c\n    p += (ptrdiff_t) clahe_info-\u003ewidth * (tile.height - 1);\n    ```\n  - Root Cause\n    \n      + If `tile.height == 0`, then `(tile.height - 1)` underflows to `UINT_MAX`.\n      + Multiplication with `clahe_info-\u003ewidth` yields a huge value close to `SIZE_MAX`.\n      + Adding this to `p` causes pointer arithmetic underflow.\n\n### **Division-by-zero**\n\n  - File / Location: `MagickCore/enhance.c`, around line 669\n\n  - Version tested: 7.1.2-8 (local ASan(undefined). /UBSan build)\n  - vulnerable code\n    \n    enhance.c: 669-673\n    \n    ```c\n     if ((image-\u003ecolumns % tile_info.width) != 0)\n        tile_info.x=(ssize_t) (tile_info.width-(image-\u003ecolumns % tile_info.width));\n      tile_info.y=0;\n      if ((image-\u003erows % tile_info.height) != 0)\n        tile_info.y=(ssize_t) (tile_info.height-(image-\u003erows % tile_info.height));\n    ```\n  - Root cause\n    \n    Missing input validation / bounds checks after computing default tile dimensions:\n    \n    If either `tile_info.width` or `tile_info.height` is 0, this triggers a division by zero. Zeros can reach this point through:\n    \n     1. Exact tiles: CLI `clahe 0x0!` (the `!` forces zero to be used verbatim).\n     2. Auto tiles on tiny images: When a requested tile is `0` (no `!`), the code derives a default from the image size (e.g., `dim \u003e\u003e 3`). For images with `dim \u003c 8`, this result is 0 unless clamped.\n\n* * *\n\n## Reproduction\n\n### **Unsigned underflow**\n\n**Environment**\n\nBuilt with AddressSanitizer and UndefinedBehaviorSanitizer enabled.\n\n```c\nexport UBSAN_OPTIONS=print_stacktrace=1:halt_on_error=1\nexport ASAN_OPTIONS=abort_on_error=1:allocator_may_return_null=1:detect_leaks=0\n```\n\n**Command**\n\n```bash\n./magick xc:black -clahe 0x0 null:\n```\n\n**Output**\n\n```\nMagickCore/enhance.c:609:6: runtime error: addition of unsigned offset overflowed\nSUMMARY: UndefinedBehaviorSanitizer: undefined-behavior MagickCore/enhance.c:609:6 in CLAHEImage\n```\n\n`./magick -size 10x10 xc:black -clahe 0x0 null:`\n\n\u003cimg width=\"1068\" height=\"64\" alt=\"image\" src=\"https://github.com/user-attachments/assets/cd9637ee-1d03-4066-834d-fda22410dd8b\" /\u003e\nmemory region corruption.\n`./magick -size 2000x2000 xc:black -clahe 0x0 null:`\n\u003cimg width=\"1069\" height=\"70\" alt=\"image\" src=\"https://github.com/user-attachments/assets/ecbab79c-a3c2-4e8c-96c9-8e2aa8f0d2b2\" /\u003e\n→ Significant memory consumption and evidence of memory region corruption.\n`./magick -size 4000x4000 xc:black -clahe 0x0 null:`\n\u003cimg width=\"776\" height=\"49\" alt=\"image\" src=\"https://github.com/user-attachments/assets/63a7cec5-616b-4aa5-87f3-a546a87e6625\" /\u003e\n→ Much larger memory usage; process appears to be aggressively consuming cache and address space.\n`./magick -size 8000x8000 xc:black -clahe 0x0 null:`\n\u003cimg width=\"748\" height=\"46\" alt=\"image\" src=\"https://github.com/user-attachments/assets/48b3aac8-98b3-4fbb-a5ca-4e7936bca44b\" /\u003e\n→ Memory usage escalates further and begins exhausting available cache.
