{"id":"DEBIAN-CVE-2026-40335","details":"libgphoto2 is a camera access and control library. Versions up to and including 2.5.33 have an out-of-bounds read in `ptp_unpack_DPV()` in `camlibs/ptp2/ptp-pack.c` (lines 622–629). The UINT128 and INT128 cases advance `*offset += 16` without verifying that 16 bytes remain in the buffer. The entry check at line 609 only guarantees `*offset \u003c total` (at least 1 byte available), leaving up to 15 bytes unvalidated. Commit 433bde9888d70aa726e32744cd751d7dbe94379a patches the issue.","modified":"2026-09-14T17:03:32.816819856Z","published":"2026-04-18T00:16:37.390Z","upstream":["CVE-2026-40335"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-40335"}],"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-2026-40335.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-2026-40335.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-2026-40335.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:L"}]}
