NVD Description
Note: Versions mentioned in the description apply only to the upstream postgresql-server package and not the postgresql-server package as distributed by RHEL.
Buffer over-read in PostgreSQL function pg_restore_attribute_stats() accepts array values of unmatched length, which causes query planning to read past end of one array. This allows a table maintainer to infer memory values past that array end. Within major version 18, minor versions before PostgreSQL 18.4 are affected. Versions before PostgreSQL 18 are unaffected.
