CVE-2026-120064

Several psqlODBC entry points use an application-supplied column number or row index as an array index without validating it. SQLBindCol with a column number above 32767 wraps the binding count negative and a later copy runs off the array. A negative SQL_DESC_COUNT on an application row descriptor unbinds columns at negative indexes. SQLColAttribute with a very large column number uses a negative index. SQLSetPos(SQL_ADD) does not check the row number against the rowset size. An application that forwards untrusted column or row numbers exposes its process to out-of-bounds reads and writes. Versions before psqlODBC 18.00.0006 are affected.
