Issue Overview:
2024-05-23: CVE-2021-32027 was added to this advisory.
2024-05-23: CVE-2023-5869 was added to this advisory.
A flaw was found in postgresql. While modifying certain SQL array values, missing bounds checks let authenticated database users write arbitrary bytes to a wide area of server memory. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2021-32027)
A flaw was found in PostgreSQL. There is an issue with incomplete efforts to operate safely when a privileged user is maintaining another user’s objects. The Autovacuum, REINDEX, CREATE INDEX, REFRESH MATERIALIZED VIEW, CLUSTER, and pg_amcheck commands activated relevant protections too late or not at all during the process. This flaw allows an attacker with permission to create non-temporary objects in at least one schema to execute arbitrary SQL functions under a superuser identity. (CVE-2022-1552)
While modifying certain SQL array values, missing overflow checks let authenticated database users write arbitrary bytes to a memory area that facilitates arbitrary code execution. Missing overflow checks also let authenticated database users read a wide area of server memory. The CVE-2021-32027 fix covered some attacks of this description, but it missed others. (CVE-2023-5869)
