{"id":"DEBIAN-CVE-2026-116723","details":"FLTK through 1.4.5 contains a stack-based buffer overflow vulnerability in Fl_BMP_Image::load_bmp_() that allows attackers to corrupt stack memory by supplying an oversized BMP colors_used field. Attackers can craft BMP or ICO files with colors_used above 256 to overflow the 768-byte colormap array, causing crashes or potential code execution.","modified":"2026-10-29T13:00:07.605483003Z","published":"2026-10-26T22:16:55.923Z","upstream":["CVE-2026-116723"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-116723"}],"affected":[{"package":{"name":"fltk1.3","ecosystem":"Debian:12","purl":"pkg:deb/debian/fltk1.3?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.11-1","1.3.11-2","1.3.11-3","1.3.8-5","1.3.8-6","1.3.8-6.1","1.3.8-6.1~exp1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-116723.json"}},{"package":{"name":"fltk1.3","ecosystem":"Debian:13","purl":"pkg:deb/debian/fltk1.3?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.11-2","1.3.11-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-116723.json"}},{"package":{"name":"fltk1.3","ecosystem":"Debian:14","purl":"pkg:deb/debian/fltk1.3?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.3.11-2","1.3.11-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-116723.json"}},{"package":{"name":"fltk1.4","ecosystem":"Debian:13","purl":"pkg:deb/debian/fltk1.4?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.3-1","1.4.4-1","1.4.4-2","1.4.4-3","1.4.4-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-116723.json"}},{"package":{"name":"fltk1.4","ecosystem":"Debian:14","purl":"pkg:deb/debian/fltk1.4?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.3-1","1.4.4-1","1.4.4-2","1.4.4-3","1.4.4-4"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-116723.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"}]}
