{"id":"JLSEC-2026-1081","summary":"ImageMagick: Integer Overflow in JNX decoder causes heap buffer over-write when processing extremly large files on 32-bit builds","details":"ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to both 6.9.13-52 and 7.1.2-27, processing an extremely large JNX file on 32-bit platforms can cause an integer overflow, leading to a heap buffer over-write. This issue has been fixed in versions 6.9.13-52 and 7.1.2-27.","modified":"2026-07-30T18:35:56.066781984Z","published":"2026-07-30T16:02:27.435Z","upstream":["CVE-2026-62946","EUVD-2026-50574","GHSA-h22j-f9xw-xjjm"],"database_specific":{"license":"CC-BY-4.0","sources":[{"imported":"2026-07-30T14:10:23.678Z","modified":"2026-07-30T00:16:25.353Z","published":"2026-07-30T00:16:25.353Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-62946","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-62946","database_specific":{"status":"Received"},"id":"CVE-2026-62946"},{"imported":"2026-07-30T14:09:11.351Z","modified":"2026-07-24T16:20:33Z","published":"2026-07-24T16:20:31Z","url":"https://api.github.com/advisories/GHSA-h22j-f9xw-xjjm","html_url":"https://github.com/advisories/GHSA-h22j-f9xw-xjjm","id":"GHSA-h22j-f9xw-xjjm"},{"published":"2026-07-30T00:06:16Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-50574","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-50574","id":"EUVD-2026-50574","imported":"2026-07-30T14:08:50.599Z","modified":"2026-07-30T00:06:16Z"}]},"references":[{"type":"WEB","url":"https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-h22j-f9xw-xjjm"},{"type":"WEB","url":"https://github.com/advisories/GHSA-h22j-f9xw-xjjm"},{"type":"WEB","url":"https://github.com/dlemstra/Magick.NET/releases/tag/14.15.0"}],"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":"7.1.2029+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-1081.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}],"credits":[{"name":"kongzhenhit-code","contact":["https://github.com/kongzhenhit-code"],"type":"REPORTER"}]}
