{"id":"DEBIAN-CVE-2026-120063","details":"When psqlODBC quotes a schema or table name into a 128-byte stack buffer, its length check lets it write up to two bytes past the end of the buffer for a long name. The names come from the application's SQL text: the table of a statement the driver parses to describe its columns, and the target of the last INSERT when the driver rewrites SELECT @@IDENTITY. In the @@IDENTITY rewrite, a column name sent by the server can also write one byte past the buffer. The bytes written past the buffer are a double quote and a NUL. An application that forwards untrusted SQL text to the driver exposes its process to stack corruption. Versions before psqlODBC 18.00.0006 are affected.","modified":"2026-11-03T09:00:06.869661812Z","published":"2026-11-02T19:18:03.557Z","upstream":["CVE-2026-120063"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-120063"}],"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-2026-120063.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-2026-120063.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-2026-120063.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:H"}]}
