{"id":"DEBIAN-CVE-2026-120067","details":"For updatable cursors, which are enabled by default, psqlODBC adds hidden ctid and, for tables with OIDs, oid columns to the query. It copies each value into a 32-byte stack buffer using the length the server sent, without checking it against the buffer size, so a value of 32 bytes or more writes past the buffer. A server not trusted under current SSL settings can send such a value. So can any database user who can create a view with its own column named ctid that the application reads with an updatable cursor. Builds with _FORTIFY_SOURCE abort; other builds overwrite adjacent stack memory. Versions before psqlODBC 18.00.0006 are affected.","modified":"2026-11-03T09:00:06.908629449Z","published":"2026-11-02T19:18:04.120Z","upstream":["CVE-2026-120067"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-120067"}],"affected":[{"package":{"name":"psqlodbc","ecosystem":"Debian:12","purl":"pkg:deb/debian/psqlodbc?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:13.02.0000-2","1:15.00.0000-1","1:16.00.0000-1","1:16.00.0005-1","1:17.00.0004-1","1:17.00.0004-2","1:17.00.0005-1","1:17.00.0006-1","1:17.00.0006-2","1:17.00.0007-1","1:17.00.0008-1","1:18.00.0001-1","1:18.00.0002-1","1:18.00.0003-1","1:18.00.0003-2","1:18.00.0004-1","1:18.00.0005-1","1:18.00.0006-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-120067.json"}},{"package":{"name":"psqlodbc","ecosystem":"Debian:13","purl":"pkg:deb/debian/psqlodbc?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:17.00.0004-2","1:17.00.0005-1","1:17.00.0006-1","1:17.00.0006-2","1:17.00.0007-1","1:17.00.0008-1","1:18.00.0001-1","1:18.00.0002-1","1:18.00.0003-1","1:18.00.0003-2","1:18.00.0004-1","1:18.00.0005-1","1:18.00.0006-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-120067.json"}},{"package":{"name":"psqlodbc","ecosystem":"Debian:14","purl":"pkg:deb/debian/psqlodbc?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:17.00.0004-2","1:17.00.0005-1","1:17.00.0006-1","1:17.00.0006-2","1:17.00.0007-1","1:17.00.0008-1","1:18.00.0001-1","1:18.00.0002-1","1:18.00.0003-1","1:18.00.0003-2","1:18.00.0004-1","1:18.00.0005-1","1:18.00.0006-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-120067.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
