提出 #19987: PostgreSQL Memory disclosure in partitioned-table UPDATE ... RETURNING情報

タイトルPostgreSQL Memory disclosure in partitioned-table UPDATE ... RETURNING
説明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. CVE-2021-32029 Fixed in 11.12, 12.7, 13.3 CVSSv3.1: 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)
