The host is installed with PostgreSQL 9.6.x before 9.6.22, 10.x before 10.17, 11.x before 11.12, 12.x before 12.7 or 13.x before 13.3 and is prone to an integer overflow vulnerability. A flaw is present in the application which fails to handle bounds checks issue while modifying certain SQL array values. Successful exploitation allows attackers to make the authenticated database users write arbitrary bytes to a wide area of server memory.
