The host is installed with PostgreSQL 9.0.x before 9.0.23, 9.1.x before 9.1.19, 9.2.x before 9.2.14, 9.3.x before 9.3.10, or 9.4.x before 9.4.5 and is prone to a denial of service vulnerability. A flaw is present in the application, which fails to handle a "too-short" salt. Successful exploitation allows attackers to cause a denial of service (server crash) or read arbitrary server memory.
