UPDATE ... RETURNING on a purpose-crafted partitioned table, an attacker can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can create prerequisite objects and complete this attack at will. A user lacking the
TEMPORARY privileges on all databases and the
CREATE privilege on all schemas typically cannot use this attack at will.
The PostgreSQL project thanks Tom Lane for reporting this problem.
