{"id":"DEBIAN-CVE-2026-42146","details":"CImg Library is a C++ library for image processing. Prior to commit c3aacf5, the nb_colors field read from the BMP file header is used directly to compute an allocation size without validating it against the remaining file size. A crafted BMP file with a large nb_colors value triggers an out-of-memory condition, crashing any application that uses CImg to load untrusted BMP files. This issue has been patched via commit c3aacf5.","modified":"2026-09-14T17:03:11.985008879Z","published":"2026-05-04T18:16:31.977Z","upstream":["CVE-2026-42146"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-42146"}],"affected":[{"package":{"name":"cimg","ecosystem":"Debian:12","purl":"pkg:deb/debian/cimg?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2.1+dfsg-1","3.2.1+dfsg-2","3.5.0+dfsg-1","3.5.2+dfsg-1","3.5.2+dfsg-2","4.0.4+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42146.json"}},{"package":{"name":"cimg","ecosystem":"Debian:13","purl":"pkg:deb/debian/cimg?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.2+dfsg-1+deb13u1"}]}],"versions":["3.5.2+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42146.json"}},{"package":{"name":"cimg","ecosystem":"Debian:14","purl":"pkg:deb/debian/cimg?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.2+dfsg-2"}]}],"versions":["3.5.2+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42146.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
