PostgreSQL 11.x < 11.12, 12.x < 12.7, 13.x < 13.3 Information Disclosure Vulnerability - Windows

PostgreSQL is prone to an information disclosure vulnerability.

Using an UPDATE ... RETURNING on a purpose-crafted partitioned table, an attacker can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can create prerequisite objects and complete this attack at will. A user lacking the CREATE and TEMPORARY privileges on all databases and the CREATE privilege on all schemas typically cannot use this attack at will.

PostgreSQL version 11.0 through 11.11, 12.0 through 12.6 and 13.0 through 13.2.

Checks if a vulnerable version is present on the target host.

Update to version 11.12, 12.7, 13.3 or later.
