{"id":"CVE-2026-26283","aliases":["GHSA-gwr3-x37h-h84v"],"url":"https://o3.security/vulnerability/CVE-2026-26283","summary":"ImageMagick has possible infinite loop in JPEG encoder when using `jpeg:extent`","details":"ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a `continue` statement in the JPEG extent binary search loop in the jpeg encoder causes an infinite loop when writing persistently fails. An attacker can trigger a 100% CPU consumption and process hang (Denial of Service) with a crafted image. Versions 7.1.2-15 and 6.9.13-40 contain a patch.","published":"2026-02-24T01:55:59.350Z","modified":"2026-08-12T03:51:42.211856570Z","cvss":{"score":6.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.00327,"percentile":0.25744,"asOf":"2026-09-15"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"NuGet","name":"Magick.NET-Q16-AnyCPU","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-AnyCPU","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-OpenMP-arm64","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-OpenMP-x64","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-arm64","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-x64","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-x86","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-OpenMP-arm64","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-OpenMP-x64","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-OpenMP-x86","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-arm64","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-x64","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-x86","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-AnyCPU","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-OpenMP-arm64","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-OpenMP-x64","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-arm64","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-x64","fixedVersion":"14.10.3"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-x86","fixedVersion":"14.10.3"}],"fix":{"url":"https://github.com/ImageMagick/ImageMagick/commit/c448c6920a985872072fc7be6034f678c087de9b","label":"ImageMagick/ImageMagick@c448c69"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/26xxx/CVE-2026-26283.json"},{"type":"ADVISORY","url":"https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-gwr3-x37h-h84v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-26283"},{"type":"WEB","url":"https://github.com/ImageMagick/ImageMagick/commit/c448c6920a985872072fc7be6034f678c087de9b"},{"type":"PACKAGE","url":"https://github.com/ImageMagick/ImageMagick"},{"type":"WEB","url":"https://github.com/dlemstra/Magick.NET/releases/tag/14.10.3"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:42.211856570Z"}}
