{"id":"DEBIAN-CVE-2026-88387","details":"LibRaw 0.22.0 contains an incorrect numeric conversion vulnerability in LibRaw::parse_tiff_ifd() when processing TIFF tag 0x00fe (NewSubfileType). A specially crafted RAW, TIFF, or DNG file can supply an attacker-controlled NewSubfileType value outside the range of a signed int. The parser converts this value and narrows it to int without performing range validation. This out-of-range conversion triggers undefined behavior, resulting in process termination and denial of service.","modified":"2026-09-27T23:00:11.556316956Z","published":"2026-09-24T21:18:57.120Z","upstream":["CVE-2026-88387"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-88387"}],"affected":[{"package":{"name":"libraw","ecosystem":"Debian:12","purl":"pkg:deb/debian/libraw?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.20.2-2.1","0.20.2-2.1+deb12u1","0.20.2-2.1+deb12u2","0.21.1-1","0.21.1-2","0.21.1-3","0.21.1-4","0.21.1-5","0.21.1-6","0.21.1-7","0.21.2-1","0.21.2-2","0.21.2-2.1","0.21.2-2.1~exp1","0.21.3-1","0.21.4-1","0.21.4-2","0.21.4-3~exp1","0.21.4-3~exp2","0.21.5b-1","0.22.0-1~exp1","0.22.1-1","0.22.1-1~exp1","0.22.1-1~exp2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88387.json"}},{"package":{"name":"libraw","ecosystem":"Debian:13","purl":"pkg:deb/debian/libraw?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.21.4-2","0.21.4-2+deb13u1","0.21.4-3~exp1","0.21.4-3~exp2","0.21.5b-1","0.22.0-1~exp1","0.22.1-1","0.22.1-1~exp1","0.22.1-1~exp2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88387.json"}},{"package":{"name":"libraw","ecosystem":"Debian:14","purl":"pkg:deb/debian/libraw?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.21.4-2","0.21.4-3~exp1","0.21.4-3~exp2","0.21.5b-1","0.22.0-1~exp1","0.22.1-1","0.22.1-1~exp1","0.22.1-1~exp2"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-88387.json"}}],"schema_version":"1.9.0"}
