Pedro Gallegos discovered that PostgreSQL incorrectly handled modifying
certain SQL array values. A remote attacker could use this issue to obtain
sensitive information, or possibly execute arbitrary code. (CVE-2023-5869)
Hemanth Sandrana and Mahendrakar Srinivasarao discovered that PostgreSQL
allowed the pg_signal_backend role to signal certain superuser processes,
contrary to expectations. (CVE-2023-5870)
