CVE-2026-120060

medium

psqlODBC trusts counts and lengths in server data in three places.

psqlODBC trusts counts and lengths in server data in three places. SQLBulkOperations uses a server-supplied row count in a size subtraction that can underflow. SQLStatistics iterates index keys using a server-supplied key count without bounding it to the fixed storage. Bytea octal decoding reads up to two bytes past the end of a truncated escape sequence. A server not trusted under current SSL settings can crash the client or make it read out of bounds. Versions before psqlODBC 18.00.0006 are affected.
