Summary
Lukas Fittl discovered that PostgreSQL incorrectly performed authorization
in the built-in pg_stats_ext and pg_stats_ext_exprs views. An unprivileged
database user can use this issue to read most common values and other
statistics from CREATE STATISTICS commands of other users.
NOTE: This update will only fix fresh PostgreSQL installations. Current
PostgreSQL installations will remain vulnerable to this issue until manual
steps are performed. Please see the instructions in the changelog located
at /usr/share/doc/postgresql-*/changelog.Debian.gz after the updated
packages have been installed, or in the PostgreSQL release notes located
here:
https://www.postgresql.org/docs/16/release-16-3.html
