Detailsinfo

A vulnerability was found in PostgreSQL psqlODBC. It has been rated as problematic. Affected by this issue is some unknown processing. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). Impacted is availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-120067 since 10/30/2026. The exploitation is known to be easy. The attack may be launched remotely. The technical details are unknown and an exploit is not available.
