Description



The PostgreSQL project reports:




Using an 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 CREATE and TEMPORARY privileges on all databases and the


CREATE privilege on all schemas typically cannot use this attack at


will.
