{"id":"DEBIAN-CVE-2026-107705","details":"Poppler 0.42.0 through 26.10.0 contains a stack-based buffer overflow in Decrypt::revision6Hash() that allows attackers controlling the password to overwrite stack memory when opening AESV3/R6 encrypted PDFs. Attackers can supply a password longer than 127 bytes through applications using the libpoppler, libpoppler-glib or C++ API to overflow the K1 and E buffers, crashing the process or corrupting memory.","modified":"2026-10-09T11:00:06.806369878Z","published":"2026-10-08T20:17:35.300Z","upstream":["CVE-2026-107705"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-107705"}],"affected":[{"package":{"name":"poppler","ecosystem":"Debian:12","purl":"pkg:deb/debian/poppler?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["22.12.0-2","22.12.0-2+deb12u1","22.12.0-2+deb12u2","22.12.0-2+deb12u3","22.12.0-2.1","22.12.0-2.2","23.08.0-1","23.08.0-2","23.12.0-1","24.02.0-1","24.02.0-2","24.02.0-3","24.02.0-4","24.02.0-5","24.02.0-5+loong64","24.06.0-1","24.06.0-2","24.08.0-1","24.08.0-2","24.08.0-3","24.08.0-4","25.01.0-1","25.01.0-2","25.01.0-3","25.01.0-4","25.01.0-5","25.03.0-1","25.03.0-10","25.03.0-11","25.03.0-11.1","25.03.0-2","25.03.0-3","25.03.0-4","25.03.0-5","25.03.0-6","25.03.0-7","25.03.0-9","26.01.0-1","26.01.0-2","26.01.0-3","26.01.0-4","26.01.0-4.1","26.01.0-5","26.07.0-1","26.07.0-2","26.07.0-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-107705.json"}},{"package":{"name":"poppler","ecosystem":"Debian:13","purl":"pkg:deb/debian/poppler?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["25.03.0-10","25.03.0-11","25.03.0-11.1","25.03.0-5","25.03.0-5+deb13u2","25.03.0-5+deb13u3","25.03.0-5+deb13u4","25.03.0-6","25.03.0-7","25.03.0-9","26.01.0-1","26.01.0-2","26.01.0-3","26.01.0-4","26.01.0-4.1","26.01.0-5","26.07.0-1","26.07.0-2","26.07.0-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-107705.json"}},{"package":{"name":"poppler","ecosystem":"Debian:14","purl":"pkg:deb/debian/poppler?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["25.03.0-10","25.03.0-11","25.03.0-11.1","25.03.0-5","25.03.0-6","25.03.0-7","25.03.0-9","26.01.0-1","26.01.0-2","26.01.0-3","26.01.0-4","26.01.0-4.1","26.01.0-5","26.07.0-1","26.07.0-2","26.07.0-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-107705.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H"}]}
