{"id":"JLSEC-2026-842","details":"The PALM image coder at `coders/palm.c` makes an improper call to AcquireQuantumMemory() in routine WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. The patch adds 256 to `bytes_per_row` in the call to AcquireQuantumMemory(). This could cause impact to reliability. This flaw affects ImageMagick versions prior to 7.0.8-68.","modified":"2026-07-30T18:23:53.756923843Z","published":"2026-07-30T16:02:27.435Z","upstream":["CVE-2020-25665"],"database_specific":{"sources":[{"id":"CVE-2020-25665","imported":"2026-07-30T14:08:42.198Z","modified":"2026-06-17T03:07:05.273Z","published":"2020-12-08T21:15:12.560Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2020-25665","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2020-25665","database_specific":{"status":"Modified"}}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1891606"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1891606"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2021/01/msg00010.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2021/01/msg00010.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/03/msg00008.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/03/msg00008.html"}],"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-2026-842.json"}}],"schema_version":"1.8.0","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"}]}
