{"id":"DEBIAN-CVE-2026-40340","details":"libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have an out-of-bounds read vulnerability in `ptp_unpack_OI()` in `camlibs/ptp2/ptp-pack.c` (lines 530–563). The function validates `len \u003c PTP_oi_SequenceNumber` (i.e., len \u003c 48) but subsequently accesses offsets 48–56, up to 9 bytes beyond the validated boundary, via the Samsung Galaxy 64-bit objectsize detection heuristic. Commit 7c7f515bc88c3d0c4098ac965d313518e0ccbe33 fixes the issue.","modified":"2026-09-14T17:03:32.835011208Z","published":"2026-04-18T00:16:38.087Z","upstream":["CVE-2026-40340"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-40340"}],"affected":[{"package":{"name":"libgphoto2","ecosystem":"Debian:12","purl":"pkg:deb/debian/libgphoto2?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.30-1","2.5.31-1","2.5.31-2","2.5.31-2.1","2.5.31-2.1~exp1","2.5.31-3","2.5.31-4","2.5.32-1","2.5.33-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40340.json"}},{"package":{"name":"libgphoto2","ecosystem":"Debian:13","purl":"pkg:deb/debian/libgphoto2?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.31-4","2.5.32-1","2.5.33-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40340.json"}},{"package":{"name":"libgphoto2","ecosystem":"Debian:14","purl":"pkg:deb/debian/libgphoto2?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.31-4","2.5.32-1","2.5.33-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40340.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"}]}
