{"id":"CVE-2026-22770","aliases":["GHSA-39h3-g67r-7g3c"],"url":"https://o3.security/vulnerability/CVE-2026-22770","summary":"ImageMagick vulnerable to Release of Invalid Pointer in BilateralBlur when memory allocation fails","details":"ImageMagick is free and open-source software used for editing and manipulating digital images. The BilateralBlurImage method will allocate a set of double buffers inside AcquireBilateralTLS. But, in versions prior to 7.1.2-13, the last element in the set is not properly initialized. This will result in a release of an invalid pointer inside DestroyBilateralTLS when the memory allocation fails. Version 7.1.2-13 contains a patch for the issue.","published":"2026-01-20T00:48:19.241Z","modified":"2026-08-12T16:24:51.255520Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"NuGet","name":"Magick.NET-Q8-x64","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-arm64","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-x86","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-OpenMP-x64","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-OpenMP-arm64","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-x64","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-arm64","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-x86","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-OpenMP-x64","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-OpenMP-arm64","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-OpenMP-x86","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-x64","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-arm64","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-x86","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-OpenMP-x64","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-OpenMP-arm64","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q8-AnyCPU","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-AnyCPU","fixedVersion":"14.10.2"},{"ecosystem":"NuGet","name":"Magick.NET-Q16-HDRI-AnyCPU","fixedVersion":"14.10.2"}],"fix":{"url":"https://github.com/ImageMagick/ImageMagick/commit/3e0330721020e0c5bb52e4b77c347527dd71658e","label":"ImageMagick/ImageMagick@3e03307"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22770.json"},{"type":"ADVISORY","url":"https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-39h3-g67r-7g3c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22770"},{"type":"FIX","url":"https://github.com/ImageMagick/ImageMagick/commit/3e0330721020e0c5bb52e4b77c347527dd71658e"},{"type":"PACKAGE","url":"https://github.com/ImageMagick/ImageMagick"},{"type":"WEB","url":"https://github.com/dlemstra/Magick.NET/releases/tag/14.10.2"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T16:24:51.255520Z"}}
