{"id":"JLSEC-2026-936","details":"ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-13 and 6.9.13-38, a heap buffer overflow vulnerability in the XBM image decoder (ReadXBMImage) allows an attacker to write controlled data past the allocated heap buffer when processing a maliciously crafted image file. Any operation that reads or identifies an image can trigger the overflow, making it exploitable via common image upload and processing pipelines. Versions 7.1.2-13 and 6.9.13-38 fix the issue.","modified":"2026-07-30T18:24:00.744272032Z","published":"2026-07-30T16:02:27.435Z","upstream":["CVE-2026-23876","EUVD-2026-3589"],"database_specific":{"sources":[{"id":"CVE-2026-23876","imported":"2026-07-30T14:08:44.647Z","modified":"2026-07-15T02:18:45.213Z","published":"2026-01-20T01:15:57.440Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-23876","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23876","database_specific":{"status":"Modified"}},{"published":"2026-01-20T01:01:38Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-3589","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-3589","id":"EUVD-2026-3589","imported":"2026-07-30T14:08:51.278Z","modified":"2026-07-15T01:17:54Z"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:3058"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-23876"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2431038"},{"type":"WEB","url":"https://github.com/ImageMagick/ImageMagick/commit/2fae24192b78fdfdd27d766fd21d90aeac6ea8b8"},{"type":"WEB","url":"https://github.com/ImageMagick/ImageMagick/security/advisories/GHSA-r49w-jqq3-3gx8"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-23876.json"}],"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-2026-936.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:H/I:H/A:H"}]}
