{"id":"ALPINE-CVE-2026-25898","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, the UIL and XPM image encoder do not validate the pixel index value returned by `GetPixelIndex()` before using it as an array subscript. In HDRI builds, `Quantum` is a floating-point type, so pixel index values can be negative. An attacker can craft an image with negative pixel index values to trigger a global buffer overflow read during conversion, leading to information disclosure or a process crash. Versions 7.1.2-15 and 6.9.13-40 contain a patch.","modified":"2026-11-03T06:33:01.910318322Z","published":"2026-02-24T02:16:01Z","upstream":["CVE-2026-25898"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-25898"}],"affected":[{"package":{"name":"imagemagick","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/imagemagick?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0-0"},{"fixed":"7.1.2.15-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-25898.json"}},{"package":{"name":"imagemagick","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/imagemagick?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0-0"},{"fixed":"7.1.2.15-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-25898.json"}},{"package":{"name":"imagemagick","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/imagemagick?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0-0"},{"fixed":"7.1.2.15-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2026-25898.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}
