{"id":"DEBIAN-CVE-2025-57807","details":"ImageMagick is free and open-source software used for editing and manipulating digital images. ImageMagick versions lower than 14.8.2 include  insecure functions: SeekBlob(), which permits advancing the stream offset beyond the current end without increasing capacity, and WriteBlob(), which then expands by quantum + length (amortized) instead of offset + length, and copies to data + offset. When offset ≫ extent, the copy targets memory beyond the allocation, producing a deterministic heap write on 64-bit builds. No 2⁶⁴ arithmetic wrap, external delegates, or policy settings are required. This is fixed in version 14.8.2.","modified":"2026-09-01T20:05:54.638589433Z","published":"2025-09-05T22:15:34.340Z","upstream":["CVE-2025-57807"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-57807"}],"affected":[{"package":{"name":"imagemagick","ecosystem":"Debian:12","purl":"pkg:deb/debian/imagemagick?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8:6.9.11.60+dfsg-1.6+deb12u4"}]}],"versions":["8:6.9.11.60+dfsg-1.6","8:6.9.11.60+dfsg-1.6+deb12u1","8:6.9.11.60+dfsg-1.6+deb12u2","8:6.9.11.60+dfsg-1.6+deb12u3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-57807.json"}},{"package":{"name":"imagemagick","ecosystem":"Debian:13","purl":"pkg:deb/debian/imagemagick?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8:7.1.1.43+dfsg1-1+deb13u2"}]}],"versions":["8:7.1.1.43+dfsg1-1","8:7.1.1.43+dfsg1-1+deb13u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-57807.json"}},{"package":{"name":"imagemagick","ecosystem":"Debian:14","purl":"pkg:deb/debian/imagemagick?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8:7.1.2.3+dfsg1-1"}]}],"versions":["8:7.1.1.43+dfsg1-1","8:7.1.1.46+dfsg1-1","8:7.1.1.47+dfsg1-1","8:7.1.1.47+dfsg1-2","8:7.1.2.1+dfsg1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2025-57807.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
