{"id":"DEBIAN-CVE-2026-4775","details":"A flaw was found in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations, potentially causing a denial of service (application crash) or arbitrary code execution.","modified":"2026-09-14T17:03:16.333046736Z","published":"2026-03-24T15:16:39.693Z","upstream":["CVE-2026-4775"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-4775"}],"affected":[{"package":{"name":"tiff","ecosystem":"Debian:12","purl":"pkg:deb/debian/tiff?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.5.0-6+deb12u4"}]}],"versions":["4.5.0-6","4.5.0-6+deb12u1","4.5.0-6+deb12u2","4.5.0-6+deb12u3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-4775.json"}},{"package":{"name":"tiff","ecosystem":"Debian:13","purl":"pkg:deb/debian/tiff?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.7.0-3+deb13u2"}]}],"versions":["4.7.0-3","4.7.0-3+deb13u1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-4775.json"}},{"package":{"name":"tiff","ecosystem":"Debian:14","purl":"pkg:deb/debian/tiff?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.7.1-2"}]}],"versions":["4.7.0-3","4.7.0-4","4.7.0-5","4.7.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-4775.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:H/I:H/A:H"}]}
