{"id":"DEBIAN-CVE-2026-25794","details":"ImageMagick is free and open-source software used for editing and manipulating digital images. `WriteUHDRImage` in `coders/uhdr.c` uses `int` arithmetic to compute the pixel buffer size. Prior to version 7.1.2-15, when image dimensions are large, the multiplication overflows 32-bit `int`, causing an undersized heap allocation followed by an out-of-bounds write. This can crash the process or potentially lead to an out of bounds heap write. Version 7.1.2-15 contains a patch.","modified":"2026-09-29T13:03:39.552425519Z","published":"2026-02-24T01:16:13.970Z","upstream":["CVE-2026-25794"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-25794"}],"affected":[{"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+deb13u6"}]}],"versions":["8:7.1.1.43+dfsg1-1","8:7.1.1.43+dfsg1-1+deb13u1","8:7.1.1.43+dfsg1-1+deb13u2","8:7.1.1.43+dfsg1-1+deb13u3","8:7.1.1.43+dfsg1-1+deb13u4","8:7.1.1.43+dfsg1-1+deb13u5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-25794.json"}},{"package":{"name":"imagemagick","ecosystem":"Debian:14","purl":"pkg:deb/debian/imagemagick?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8:7.1.2.15+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","8:7.1.2.12+dfsg1-1","8:7.1.2.13+dfsg1-1","8:7.1.2.3+dfsg1-1","8:7.1.2.7+dfsg1-1","8:7.1.2.8+dfsg1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-25794.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:L/I:N/A:H"}]}
