Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for PostgreSQL/psqlODBC.
  2. 2Review the reported fix. Source-reported solution: Upgrade to psqlODBC 18.00.0006 or later. The row count, the index-key count, and the octal escape length are checked before use.

Sources and claim methodology

  • GitHub security advisorygithub.com
Upstream source description

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.
