Title:	PostgreSQL 12.x < 12.18, 13.x < 13.14, 14.x < 14.11, 15.x < 15.6, 16.x < 16.1 Privilege Escalation Vulnerability - Linux
Summary:	PostgreSQL is prone to a privilege escalation vulnerability.
Description:	Summary: PostgreSQL is prone to a privilege escalation vulnerability. Vulnerability Insight: Late privilege drop in REFRESH MATERIALIZED VIEW CONCURRENTLY in PostgreSQL allows an object creator to execute arbitrary SQL functions as the command issuer. The command intends to run SQL functions as the owner of the materialized view, enabling safe refresh of untrusted materialized views. The victim is a superuser or member of one of the attacker's roles. The attack requires luring the victim into running REFRESH MATERIALIZED VIEW CONCURRENTLY on the attacker's materialized view. As part of exploiting this vulnerability, the attacker creates functions that use CREATE RULE to convert the internally-built temporary table to a view. Affected Software/OS: PostgreSQL version 12.x prior to 12.18, 13.x prior to 13.14, 14.x prior to 14.11 and 15.x prior to 15.6. The only known exploit does not work in PostgreSQL 16 and later. For defense in depth, PostgreSQL 16.2 adds the protections that older branches are using to fix their vulnerability. Solution: Update to version 12.18, 13.14, 14.11, 15.6 or later.
