Summary: psqlODBC stack buffer overflow when quoting long schema and table names
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.
