FreeBSD : PostgreSQL -- Memory disclosure in partitioned-table UPDATE ... RETURNING (76e0bb86-b4cb-11eb-b9c9-6cc21735f730)

high Nessus Plugin ID 149514

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The PostgreSQL project reports :

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.

Solution

Update the affected packages.
