{"id":"JLSEC-2026-994","summary":"ImageMagick has a heap overflow caused by integer overflow/wraparound in viff encoder on 32-bit builds","details":"ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below both 7.1.2-19 and 6.9.13-44, the viff encoder contains an integer truncation/wraparound issue on 32-bit builds that could trigger an out of bounds heap write, potentially causing a crash. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19.","modified":"2026-07-30T18:35:41.927292105Z","published":"2026-07-30T16:02:27.435Z","upstream":["CVE-2026-33900","EUVD-2026-22102","GHSA-v67w-737x-v2c9"],"database_specific":{"license":"CC-BY-4.0","sources":[{"id":"CVE-2026-33900","imported":"2026-07-30T14:08:46.621Z","modified":"2026-06-17T10:38:17.073Z","published":"2026-04-13T21:16:25.333Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-33900","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33900","database_specific":{"status":"Analyzed"}},{"html_url":"https://github.com/advisories/GHSA-v67w-737x-v2c9","id":"GHSA-v67w-737x-v2c9","imported":"2026-07-30T14:10:13.332Z","modified":"2026-04-24T20:47:14Z","published":"2026-04-13T19:09:58Z","url":"https://api.github.com/advisories/GHSA-v67w-737x-v2c9"},{"modified":"2026-04-14T16:28:41Z","published":"2026-04-13T20:50:19Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-22102","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-22102","id":"EUVD-2026-22102","imported":"2026-07-30T14:08:53.955Z"}]},"references":[{"type":"WEB","url":"https://github.com/ImageMagick/ImageMagick/commit/d27b840a61b322419a66d0d192ff56d52498148d"},{"type":"WEB","url":"https://github.com/ImageMagick/ImageMagick/releases/tag/7.1.2-19"},{"type":"WEB","url":"https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-v67w-737x-v2c9"},{"type":"WEB","url":"https://github.com/advisories/GHSA-v67w-737x-v2c9"},{"type":"WEB","url":"https://github.com/dlemstra/Magick.NET/releases/tag/14.12.0"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33900"}],"affected":[{"package":{"name":"ImageMagick_jll","ecosystem":"Julia","purl":"pkg:julia/ImageMagick_jll?uuid=c73af94c-d91f-53ed-93a7-00f77d67a9d7"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"7.1.2023+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-994.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}],"credits":[{"name":"shitianyu-2004","contact":["https://github.com/shitianyu-2004"],"type":"REPORTER"}]}
