{"id":"JLSEC-2026-851","details":"There are several memory leaks in the MIFF coder in `/coders/miff.c` due to improper image depth values, which can be triggered by a specially crafted input file. These leaks could potentially lead to an impact to application availability or cause a denial of service. It was originally reported that the issues were in `AcquireMagickMemory()` because that is where LeakSanitizer detected the leaks, but the patch resolves issues in the MIFF coder, which incorrectly handles data being passed to `AcquireMagickMemory()`. This flaw affects ImageMagick versions prior to 7.0.9-0.","modified":"2026-07-30T18:23:45.369146863Z","published":"2026-07-30T16:02:27.435Z","upstream":["CVE-2020-27753"],"database_specific":{"license":"CC-BY-4.0","sources":[{"url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2020-27753","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2020-27753","database_specific":{"status":"Modified"},"id":"CVE-2020-27753","imported":"2026-07-30T14:08:42.523Z","modified":"2026-06-17T03:09:34.680Z","published":"2020-12-08T22:15:18.133Z"}]},"references":[{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1894229"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1894229"}],"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":"6.9.12+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-851.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V2","score":"AV:N/AC:M/Au:N/C:N/I:N/A:P"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
