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. This issue has been patched in version 7.1.2-8.","state":0,"publishedAt":"2025-10-27T20:00:33.205+00:00","modifiedAt":"2025-10-27T20:23:20.526+00:00","affected":[{"ecosystem":"Vendor product","name":"ImageMagick","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"ImageMagick\",\n                    \"product\": \"ImageMagick\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 7.1.2-8\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H","score":4.7,"severity":"MEDIUM"}],"references":["https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-wpp4-vqfq-v4hp","https://github.com/ImageMagick/ImageMagick/commit/7b47fe369eda90483402fcd3d78fa4167d3bb129"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-62594","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-62594","identifiers":["CVE-2025-62594"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
