Generate an SVG file\n\n2. Read this file using Magick:\n\n```\n./magick /data/ylwang/Tools/LargeScan/targets/ImageMagick/test++/1.svg null\n```\n\n3. Causes a DoS Attack\n\nMy server has a large amount of memory, causing a stack overflow to take a long time. I'll use the Windows release version as an example:\n\n``` \nPS C:\\Program Files\\ImageMagick-7.1.2-Q8> .\\magick.exe -ping 1.svg null:\nPS C:\\Program Files\\ImageMagick-7.1.2-Q8> echo $LASTEXITCODE\n-1073741571\n```\n\nThe error code -1073741571 indicates a crash due to a stack overflow.\n\n### Impact\n\nThis is a DoS vulnerability and all applications using Magick to parse SVG files are affected.","published":"2025-12-30T16:14:24.235Z","modified":"2026-08-12T15:14:53.672035Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"epss":{"score":0.00632,"percentile":0.48481,"asOf":"2026-09-15"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"NuGet","name":"Magick.NET-Q16-AnyCPU","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-AnyCPU","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-x86","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-x86","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-AnyCPU","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-x86","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-arm64","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-OpenMP-x64","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-OpenMP-arm64","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-x64","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-arm64","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-OpenMP-x64","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-OpenMP-arm64","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-x64","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-arm64","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-OpenMP-x64","fixedVersion":"14.10.1"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-OpenMP-arm64","fixedVersion":"14.10.1"}],"fix":{"url":"https://github.com/ImageMagick/ImageMagick/commit/6f431d445f3ddd609c004a1dde617b0a73e60beb","label":"ImageMagick/ImageMagick@6f431d4"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/68xxx/CVE-2025-68618.json"},{"type":"ADVISORY","url":"https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-p27m-hp98-6637"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68618"},{"type":"FIX","url":"https://github.com/ImageMagick/ImageMagick/commit/6f431d445f3ddd609c004a1dde617b0a73e60beb"},{"type":"PACKAGE","url":"https://github.com/ImageMagick/ImageMagick"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T15:14:53.672035Z"}}
