{"id":"DEBIAN-CVE-2026-12912","details":"A flaw was found in libtiff. A remote attacker could exploit this vulnerability by providing a specially crafted PixarLog-compressed TIFF image. This issue occurs when decoding Pixarlog codec images with the PIXARLOGDATAFMT_8BITABGR output format and a specific stride value, leading to a heap-based buffer overflow. This could potentially result in arbitrary code execution or a denial of service (DoS).","modified":"2026-09-22T08:47:26.843265662Z","published":"2026-06-29T17:16:28.230Z","upstream":["CVE-2026-12912"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-12912"}],"affected":[{"package":{"name":"tiff","ecosystem":"Debian:12","purl":"pkg:deb/debian/tiff?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.5.0-6","4.5.0-6+deb12u1","4.5.0-6+deb12u2","4.5.0-6+deb12u3","4.5.0-6+deb12u4","4.5.1+git230720-1","4.5.1+git230720-2","4.5.1+git230720-3","4.5.1+git230720-4","4.5.1+git230720-5","4.5.1-1","4.5.1~rc3-1","4.6.0-1","4.6.0-2","4.7.0-1","4.7.0-2","4.7.0-3","4.7.0-4","4.7.0-5","4.7.1-1","4.7.1-2","4.7.1-3","4.7.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-12912.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+deb13u3"}]}],"versions":["4.7.0-3","4.7.0-3+deb13u1","4.7.0-3+deb13u2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-12912.json"}},{"package":{"name":"tiff","ecosystem":"Debian:14","purl":"pkg:deb/debian/tiff?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.7.2-1"}]}],"versions":["4.7.0-3","4.7.0-4","4.7.0-5","4.7.1-1","4.7.1-2","4.7.1-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-12912.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H"}]}
