{"id":"CVE-2026-25982","aliases":["GHSA-pmq6-8289-hx3v"],"url":"https://o3.security/vulnerability/CVE-2026-25982","summary":"ImageMagick Has Heap Out-of-Bounds Read in DCM Decoder (ReadDCMImage)","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 heap out-of-bounds read vulnerability exists in the `coders/dcm.c` module. When processing DICOM files with a specific configuration, the decoder loop incorrectly reads bytes per iteration. This causes the function to read past the end of the allocated buffer, potentially leading to a Denial of Service (crash) or Information Disclosure (leaking heap memory into the image). Versions 7.1.2-15 and 6.9.13-40 contain a patch.","published":"2026-02-24T01:40:45.433Z","modified":"2026-08-07T11:50:31.941252275Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L"},"epss":null,"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-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-Q16-HDRI-OpenMP-x64","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":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/25xxx/CVE-2026-25982.json"},{"type":"ADVISORY","url":"https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-pmq6-8289-hx3v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-25982"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:31.941252275Z"}}
