{"id":"JLSEC-2026-971","summary":"ImageMagick has a heap Buffer Over-read in its DJVU image format handler","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 buffer over-read vulnerability exists in the DJVU image format handler. The vulnerability occurs due to integer truncation when calculating the stride (row size) for pixel buffer allocation. The stride calculation overflows a 32-bit signed integer, resulting in an out-of-bounds memory reads. Versions 7.1.2-15 and 6.9.13-40 contain a patch.","modified":"2026-07-30T18:35:55.115275978Z","published":"2026-07-30T16:02:27.435Z","upstream":["CVE-2026-27799","EUVD-2026-8772","GHSA-r99p-5442-q2x2"],"database_specific":{"sources":[{"published":"2026-02-26T00:16:25.393Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-27799","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27799","database_specific":{"status":"Analyzed"},"id":"CVE-2026-27799","imported":"2026-07-30T14:08:45.820Z","modified":"2026-06-17T10:27:42.203Z"},{"url":"https://api.github.com/advisories/GHSA-r99p-5442-q2x2","html_url":"https://github.com/advisories/GHSA-r99p-5442-q2x2","id":"GHSA-r99p-5442-q2x2","imported":"2026-07-30T14:09:23.207Z","modified":"2026-02-27T22:17:07Z","published":"2026-02-25T19:24:24Z"},{"modified":"2026-02-26T17:04:08Z","published":"2026-02-25T23:20:25Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-8772","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-8772","id":"EUVD-2026-8772","imported":"2026-07-30T14:08:55.036Z"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://github.com/ImageMagick/ImageMagick/commit/e87695b3227978ad70b967b8d054baaf8ac2cced"},{"type":"WEB","url":"https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-r99p-5442-q2x2"},{"type":"WEB","url":"https://github.com/advisories/GHSA-r99p-5442-q2x2"},{"type":"WEB","url":"https://github.com/dlemstra/Magick.NET/releases/tag/14.10.3"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27799"}],"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-2026-971.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L"}]}
