{"id":"DEBIAN-CVE-2026-23876","details":"ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-13 and 6.9.13-38, a heap buffer overflow vulnerability in the XBM image decoder (ReadXBMImage) allows an attacker to write controlled data past the allocated heap buffer when processing a maliciously crafted image file. Any operation that reads or identifies an image can trigger the overflow, making it exploitable via common image upload and processing pipelines. Versions 7.1.2-13 and 6.9.13-38 fix the issue.","modified":"2026-09-14T17:02:57.596033069Z","published":"2026-01-20T01:15:57.440Z","upstream":["CVE-2026-23876"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-23876"}],"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+deb12u6"}]}],"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","8:6.9.11.60+dfsg-1.6+deb12u4","8:6.9.11.60+dfsg-1.6+deb12u5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-23876.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+deb13u5"}]}],"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"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-23876.json"}},{"package":{"name":"imagemagick","ecosystem":"Debian:14","purl":"pkg:deb/debian/imagemagick?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8:7.1.2.13+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","8:7.1.2.3+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/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-23876.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"}]}
