Corrective updates have been released for all supported branches of PostgreSQL 16.4, 15.8, 14.13, 13.16, 12.20, addressing 56 bugs identified over the last three months. Among other issues, the new versions have patched a vulnerability (CVE-2024-7348) categorized as critical (risk level 8.8 out of 10). This vulnerability arises from a race condition in the pg_dump utility, allowing an attacker, who has the ability to create and delete persistent objects in the database, to execute arbitrary SQL code with the privileges of the user running the pg_dump utility (usually, pg_dump is run with superuser privileges for database backups). <\/p>\n

For a successful attack, it's necessary to track the moment the pg_dump utility starts, which can easily be achieved through manipulations with an open transaction. The attack involves replacing a sequence with a view or an external table that defines the SQL code being executed at the moment pg_dump is launched, when information about the existence of the sequence has already been obtained but the data has not yet been output. To address the vulnerability, the 'restrict_nonsystem_relation_kind' setting has been added, which prohibits the exposure of non-system views and access to external tables in pg_dump.
