Amazon Linux 2 Security Advisory: ALASPOSTGRESQL12-2023-003
Advisory Release Date: 2023-08-07 05:59 Pacific
Advisory Updated Date: 2023-09-25 22:07 Pacific
Severity:
Important
Issue Overview:
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)
