Noah Misch 681d9e4621 Replace last PushOverrideSearchPath() call with set_config_option(). ... The two methods don't cooperate, so set_config_option("search_path", ...) has been ineffective under non-empty overrideStack. This defect enabled an attacker having database-level CREATE privilege to execute arbitrary code as the bootstrap superuser. While that particular attack requires v13+ for the trusted extension attribute, other attacks are feasible in all supported versions. Standardize on the combination of NewGUCNestLevel() and set_config_option("search_path", ...). It is newer than PushOverrideSearchPath(), more-prevalent, and has no known disadvantages. The "override" mechanism remains for now, for compatibility with out-of-tree code. Users should update such code, which likely suffers from the same sort of vulnerability closed here. Back-patch to v11 (all supported versions). Alexander Lakhin. Reported by Alexander Lakhin. Security: CVE-2023-2454		2023-05-08 06:14:07 -07:00
