{"id":"DEBIAN-CVE-2026-18090","details":"A flaw was found in gdk-pixbuf. This vulnerability allows a remote attacker to cause a heap out-of-bounds read by providing a specially crafted Apple Icon Image (.icns) file. The uncompress() function, which handles RLE-encoded ICNS icon data, fails to validate the source buffer's boundaries during decompression. This can lead to a denial of service, where the application crashes, or to information disclosure, potentially revealing sensitive data from adjacent memory.","modified":"2026-09-15T08:47:38.383610475Z","published":"2026-09-08T23:17:22.760Z","upstream":["CVE-2026-18090"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-18090"}],"affected":[{"package":{"name":"gdk-pixbuf","ecosystem":"Debian:12","purl":"pkg:deb/debian/gdk-pixbuf?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.42.10+dfsg-1","2.42.10+dfsg-1+deb12u1","2.42.10+dfsg-1+deb12u2","2.42.10+dfsg-1+deb12u3","2.42.10+dfsg-1+deb12u4","2.42.10+dfsg-2","2.42.10+dfsg-3","2.42.12+dfsg-1","2.42.12+dfsg-2","2.42.12+dfsg-3","2.42.12+dfsg-4","2.42.12+dfsg-5","2.44.3+dfsg-1","2.44.3+dfsg-2","2.44.3+dfsg-3","2.44.4+dfsg-1","2.44.4+dfsg-2","2.44.4+dfsg-3","2.44.5+dfsg-1","2.44.5+dfsg-2","2.44.5+dfsg-3","2.44.5+dfsg-4","2.44.6+dfsg-1","2.44.6+dfsg-2","2.44.7+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-18090.json"}},{"package":{"name":"gdk-pixbuf","ecosystem":"Debian:13","purl":"pkg:deb/debian/gdk-pixbuf?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.42.12+dfsg-4","2.42.12+dfsg-4+deb13u1","2.42.12+dfsg-5","2.44.3+dfsg-1","2.44.3+dfsg-2","2.44.3+dfsg-3","2.44.4+dfsg-1","2.44.4+dfsg-2","2.44.4+dfsg-3","2.44.5+dfsg-1","2.44.5+dfsg-2","2.44.5+dfsg-3","2.44.5+dfsg-4","2.44.6+dfsg-1","2.44.6+dfsg-2","2.44.7+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-18090.json"}},{"package":{"name":"gdk-pixbuf","ecosystem":"Debian:14","purl":"pkg:deb/debian/gdk-pixbuf?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.42.12+dfsg-4","2.42.12+dfsg-5","2.44.3+dfsg-1","2.44.3+dfsg-2","2.44.3+dfsg-3","2.44.4+dfsg-1","2.44.4+dfsg-2","2.44.4+dfsg-3","2.44.5+dfsg-1","2.44.5+dfsg-2","2.44.5+dfsg-3","2.44.5+dfsg-4","2.44.6+dfsg-1","2.44.6+dfsg-2","2.44.7+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-18090.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:L/I:N/A:H"}]}
